Purpose – The paper provides a detailed description of standard procedures for constructing facial composites. These procedures are relevant to forensic practice and are contained in the technical papers of this special issue; the purpose of this paper is also to provide an expanding reference of procedures for future research on facial composites and facial-composite systems. Design/methodology/approach – A detailed account is given of the interaction between practitioner and witness for producing a facial composite. This account involves an overview of the Cognitive Interview (CI) and the Holistic CI (H-CI) techniques used to obtain a description of the face of an offender (target); the authors then describe how this information is used to produce a composite from five popular face-production systems: Sketch, PRO-fit, Electronic Facial Identification Technique (E-FIT), EvoFIT and EFIT-V. An online annex is also made available to provide procedural information for additional composite systems. Practical implications – The work is valuable to forensic practitioners and researchers as a reference for interviewing techniques (involving a CI or an H-CI) and using facial-composite systems. Originality/value – The authors provide an accessible, current guide for how to administer interviewing techniques and how to construct composites from a range of face-production systems.

Composite mast with rigging system is an example of a complex composite-steel system. The implementation of modern constructional materials such as composite materials in order to construct the composite masts has some consequences. Composites have different properties than materials such as wood (in the past), steel or aluminium which are usually used in construction of the masts.

Purpose – The introduction of a three-quarter-view database in the PRO-fit facial-composite system has enabled an investigation into the effects of image view in face construction. The purpose of this paper is to examine the impact of constructing full-face and three-quarter-view composites under different encoding conditions. It also examines the potential value of three-quarter-view composites that can be generated automatically from a front-view composite. The authors also investigate whether there is an identification benefit for presenting full-face and three-quarter composites together. Design/methodology/approach – Three experiments examine the impact of encoding conditions on composite construction and presentation of composites at the evaluation stage. Findings – The work revealed that while standard full-face composites perform well when all views of the face have been encoded, care should be taken when a person has only seen one view. When a witness has seen a side view of a suspect, a three-quarter-view composite should be constructed. Also, it would be beneficial for a witness to construct two composites of a suspect, one in full-face view and one in a three-quarter-view, particularly when the witness has only encoded one view. No benefit emerged for use of three-quarter-view composites generated automatically. Research limitations/implications – This is the first study to examine viewpoint in facial composite construction. While a great deal of research has examined viewpoint dependency in face recognition tasks, composite construction is a reconstruction task involving both recall and recognition. The results indicate that there is a viewpoint effect that is similar to that described in the recognition literature. However, more research is needed in this area. Practical implications – The practical implications of this research are that it is extremely important for facial composite operators in the field (police operators) to know who will make a good likeness of the target. Research such as this which examines real-life issues is incredibly important. This research shows that if a witness has seen all views of a perpetrator’s face then standard composite construction using a full-face view will work well. However, if they have only seen a single view then it will not. Social implications – There are obvious wider societal implications for any research which deals with eyewitness memory and the potential identification of perpetrators. Originality/value – No research to date has formally examined the impact of viewpoint in facial-composite construction.

Purpose – The purpose of this paper is to investigate whether the presence of a whole-face context during facial composite production facilitates construction of facial composite images. Design/methodology/approach – In Experiment 1, constructors viewed a celebrity face and then developed a facial composite using PRO-fit software in one of two conditions: either the full-face was visible while facial features were selected, or only the feature currently being selected. The composites were named by different participants. The authors then replicated the study using a more forensically valid procedure: in Experiment 2 non-football fans viewed an image of a premiership footballer and 24 hours later constructed a composite of the face with a trained software operator. The resulting composites were named by football fans. Findings – In both studies, the presence of the facial context promoted more identifiable facial composites. Research limitations/implications – Current composite software was deployed in a conventional and unconventional way to demonstrate the importance of facial context. Practical implications – Results confirm that composite software should have the whole-face context visible to witnesses throughout construction. Although some software systems do this, there remain others that present features in isolation and these findings show that these systems are unlikely to be optimal. Originality/value – This is the first study to demonstrate the importance of a full-face context for the construction of facial composite images. Results are valuable to police forces and developers of composite software.

ABSTRACT
This research discussing about decision support system analysis in determining concrete and composit road construction compared to asphalt construction for the case of roads in North Maluku Province. This study uses the Analytic Hierarchy Process (AHP) method or model as a method to analyze the feasibility of concrete and composit construction compared to asphalt construction. There are at least 7 (seven) factors that are considered as AHP inputs, namely road conditions, technical pavement, ecomonical/cost, duration/method of construction, availability of equipment, environmental conditions, and availability of materials. This study method includes data collection and analysis methods. For data collection, this study uses a questionnaire method that contains questions related to technical and non-technical factors that are used to assess the feasibility of a road for selecting a type of road pavement with flexible or rigid pavement. The construction feasibility of concrete and composite pavements is better than that of flexible asphalt pavements on road constructions, with the following sub-criteria conditions; roads that have bends and inclines, lower road maintenance costs, excellent weather and environmental resistance, less dense traffic, easy work execution and can be done at any time, do not require a lot of AMP and equipment, and asphalt availability can't fast time. The alternative of road pavement type is effective as a weight value of 33.78% with using the composite pavement construction.

In small vessels, for example, yachts, polymer–glass composites are mainly used for their construction. However, the disposal and/or recycling of composite units is very difficult. It is advisable to solve the problem of disposing of post-consumer items as soon as possible. Therefore, alternative, environmentally friendly, but also durable and safe construction materials are being sought. Such materials can be polymer–natural composites, which can be used as a potential material (alternative to polymer–glass composites) for the construction of small vessels. However, its performance properties should be investigated as new construction materials. The possibility of using polymer–hemp composites was assessed in terms of safety, i.e., the fire resistance of these materials. This paper compares selected characteristics that the reaction of composite materials has to fire with glass fiber and hemp fiber reinforcements. During the study, a natural composite reinforced with hemp fabric was investigated. Based on the laboratory test, it was found that this composite showed better susceptibility to energy recycling, with a relatively small deterioration in fire resistance compared to the composite reinforced with glass fiber. This material could therefore be a potential construction material for small vessels if we consider fire resistance in terms of the safety of the vessel’s operation.

As the world business enlarging day by day, and designing of the buildings are getting complex and demanding more technology to enhance its stability, performances, cost, duration and its uniqueness of designing. At the later part of development in civil engineer majority of the work was transformed from conventional system to a well organized and computerized system, most of the time the company employees and owners were in live risk, due to non availability of technology. As time goes technology develops, having this in mind we had also suggested using Etabs software in our design. Etabs is a 3D analysis and designing of the buildings, it is engineering software which is used in construction and designing or analysis of complex multi stored buildings. Composite column is actually the amalgamation of two traditionally methodologies structure steel and structure concrete, their design could be based on concrete or steel methodology. Any method can be used to develop composite column approach. Composite columns are designed by applying different components of structure steel and concrete in according to use the advantages and property of each material. The outer and inner behavior of the concrete and structural steel ingredients make the Composite column is very unbending, enough squashy, cost effective and generally makes it efficient partner of the building and bride constructions. Normally three kinds of composite column sections are using in high risky building construction. The building was analyzed by using Etabs and designed according to the needed requirement. Composite column technology for construction of building is now a day’s very popular and has more advantages over the conventional designing of buildings, currently we see tall buildings with great advantages such as less space more accommodation, parking, and many more, these all can only be achieved if we implement the concept and idea of composite construction. This is why composite construction is so good; the one line reason behind this is that it combines both steel and concrete into one unit. By combining these materials can strengthen and provide best result in extremely enough and light weight design. Composite by column can also save our time and we can construction the complex buildings in short term. One of the biggest achievement if is done in construction by composite column is the cost reduction, because most of the constructions companies are being lost and dropped its position due to non profitability.

AbstractThe article presents the basic properties of composite materials used for the construction of special ships. Static and dynamic characteristics of materials such as wood and polyester-glass composites are presented. Noteworthy are materials such as surface modified wood and polyester-glass composites with the addition of recyclate. Composite materials are widely used materials for the construction of non-magnetic warships. The article describes the properties of surface modified wood with polymethyl methacrylate and a polyester-glass composite with the addition of recyclate. The recyclate is fragmented, milled polyester-glass scrap. The content of the recyclate greatly affects the mechanical properties of the composite. The properties of the composite with the addition of recyclate depend on the recyclate content as well as the production technology and size of the recycled granulates. The test results showed that the increase in the recycled content causes a decrease in the mechanical properties of the composite. However, it should be remembered that these materials originated from waste, waste that is not subject to self-degradation, which have a very negative impact on the natural environment. At present, where there is a very large pollution of the natural environment, the processing and management of huge amounts of composite waste is an essential goal. A significant amount of recyclate significantly reduces the mechanical properties of the composite; however, the same large amount of recycled material has been transformed and used. The manufactured material and its structural elements are still non-magnetic structures and can be used on a less loaded element. The choice of material for the construction of special ships elements is determined not only by its properties but also by knowledge, experience, method of processing, economic and technical risk.

Over the past twenty years several hundred articles on analysis and behavior of semi-rigid steel frames have appeared in the technical literature.1 This body of knowledge indicates that semi-rigid or partially restrained (PR) frames possess many economical, constructional, and technical advantages over rigid frames and frame-shear wall systems. However, it is safe to say that only a small percentage of the literature on this subject addresses design issues directly.2—5 The result is that even though semi-rigid or partial-restraint (PR) connection behavior is recognized and allowed by most specifications, very few structural engineers have made explicit use of them in design.6 In general these few designers possess what are considered advanced analysis and design tools, consisting mostly of computer programs developed inhouse. This situation is beginning to change, however, because advanced analysis techniques7,8 are beginning to be widely discussed and disseminated and public-domain and commercial programs incorporating them will soon be available. This paper describes the development of a particular type of semi-rigid construction which the author and his coworkers have developed over the past 10 years. The paper is divided into three main parts. The first part presents some important considerations on semi-rigid behavior which apply irrespective of the connection type being used. They are included here to illustrate the differences between simple, fully rigid, and partially rigid structures and to highlight their impact on limit states. The second part of the paper deals with the design of semi-rigid structures utilizing the composite action of the floor system.

Composite materials, particularly fiberglass, have created a revolution in commercial marine design and construction over the past 20 to 30 years. The U.S. Navy, however, has been slow in recognizing the value of composite materials and implementing their use. The current construction of a fiberglass minesweeper will introduce composites into the auxiliary Navy, but major surface combatants have yet to take advantage of their unique material properties. The Integrated Technology Deckhouse (ITD) Project has been steadily progressing toward the goal of constructing naval combatant deckhouses out of an integrated system of steel and composites. The approach of the ITD Project has resolved problems and issues in phases, with each phase becoming progressively narrower in scope and greater in detail. The first phase of the project was primarily a materials and structural concepts trade-off study. Material properties were reviewed for a variety of fiberglass composites and design concepts, resulting in a tradeoff matrix. The second phase included a shipyard producibility study. Issues associated with working with composites in a modular, steel construction environment were addressed. Recommendations from this study were then addressed in detail in a follow-on producibility study. In the most recently completed study, the producibility issues associated with the design and construction of the DDG-51 Class forward Close In Weapons System (CIWS) maintenance enclosure were addressed. This paper reviews the progress to date in the ITD project, highlighting the significant issues and explaining why some of the major decisions were made. Emphasis is placed on the most recent phase of the project, which concentrated on a specific ship unit.

The article is devoted to the research into the utilization of large volume industrial wastes to produce mineral-polymer composite construction materials. To produce the composites, polyvinyl chloride wastes have been suggested as binding thermoplastic matrix and ash-and-slag wastes, which are the by-product of coal combustion at TPP of Irkutsk Oblast, as mineral filler. Since the problem of accumulation and storage, such as large volumes of power generation industry wastes is becoming more and more serious, the recycling of these wastes with the production of useful products is the vital task. Plants that manufacture products from PVC also produce plastic wastes in the form of rejected and substandard raw material, which can be recycled. At the same time, the problem of production available construction materials for the Baikal region from the local cheap raw material is solved. The team of Irkutsk National Research Technical University has conducted a number of the industrial trials on the production of mineral-polymer composites by the method of extrusion. As a result, the principal opportunity of co-utilization of PVC wastes and ash-and-slag materials during the production of composite construction materials has been testified. Local construction companies can use the produced materials.

Steel-concrete composite constructions in Bangladesh are nowadays very popular owing to their advantages over conventional concrete and steel constructions. Concrete structures are massive and allot more seismic weight and less deflection whereas steel structures instruct more deflections and ductility to the structure, which is beneficial in resisting earthquake and wind forces. Composite construction combines the better properties of both steel and concrete along with lesser cost, speedy construction, fire protection etc. The objective of this study was to analysis and design ground floor plus 19 storied R.C.C, Steel and Composite (steel-concrete) multi-storied parking structure’s frame of same plan using ETABS 2013 software and compare their structural parameters with estimated cost for required material. All frames are designed for same gravity and dynamic loadings. The RCC deck-slab is used in steel and composite frame. Beam and column sections are made of RCC, steel or steel-concrete composite sections. The composite construction option provided about 25 % and 18% less cost when compared to RCC and steel structure, respectively. Comparative study concludes that the composite frames are best suited among all the three types of constructions in terms of material cost and benefit added with better structural behaviour.

In India, plain concrete is a common building material, especially for medium- and low-rise buildings. Even while steel is still widely used in high-rise structures and composite construction is less frequent, it's possible that composite construction could prove more beneficial in these projects. Reinforced concrete is often used in construction projects. Steel beams are put into concrete to make reinforced concrete, an efficient composite material. The distinguishing feature of composite construction is the secure joining and bending of two load-bearing structural elements into a single piece. When compared to RCC most steel frames, composite constructions are considered to be some of the least expensive and transient building materials. The main component of a composite construction is an I-section column embedded or encased in building materials, or a tube of steel filled with steel and concrete. Composed of cold steel plates plus mortar, Part I consists of a beam plus a plate for the deck. The beams are connected to the top slab using fire-resistant and robust shear connections.

Abstract: Fiber reinforced polymer composite is a relatively new construction material that is slowly gaining traction among civil engineers. Bridge engineering is one of the civil engineering sectors that has benefited from the advent of FRP composite materials. Its advantages over traditional construction materials include a high tensile strength-to-weight ratio, the capacity to be moulded into diverse shapes, and potential resilience to weather conditions, all of which could result in lower maintenance costs. FRP composite is a suitable solution for creative construction because of these features. Experiments on the applicability of FRP composite in bridge structures have been undertaken over the last ten years, including FRP composite girder and bridge deck applications, column and beam strengthening, and so on. The basic knowledge of FRP composites, including mechanical characteristics and manufacturing procedures important to civil engineering applications, will be presented initially in this document. Following that, three case studies will be used to study the use of FRP composites in bridge engineering. At the conclusion, four major factors contributing to the material's sluggish acceptance in the construction sector as whole, despite its success in the aerospace and automobile industries, are discussed.

High-rise construction typically implies a multi-storey structure approximately between forty to hundred and twenty meters tall (approximately twelve to forty storeys). On the other hand, composite materials are those made from two or more constituents generally with considerably dissimilar physical or chemical compositions. The focal point in this paper is in-particular on high-rise construction and whether or not composite materials’ structural integrity, and long-term sustainability, is comparable to that of a traditional building. To assess the composite materials’ structural integrity, Structural Health Monitoring (SHM) will also be utilised. While, composites possess different characteristics from those common to traditional materials; the universal purpose of producing such materials is to produce matters, which are stronger, lighter, and commonly less expensive. Generally, in construction, the composite materials typically include geo-polymers, fiber-reinforced concrete and others. For high-rise construction, these composite materials require to bear a variety of demanding conditions, including high winds and seismic conditions, which are important design factors for such structures. Nevertheless, a particular benefit of composite materials for high rise construction is their overall ability to maintain structural integrity despite their lack of conventional composition. The composite materials are traditionally utilised for high-rise buildings in order to reinforce the overall structural integrity. Accordingly, this paper will also include a number of case studies to support the ever-increasing utilization of composite materials for high-rise construction.

Steel concrete composite construction has gained wide acceptance worldwide as an alternative to pure steel and pure concrete construction. The use of steel in construction industry is very low in Nepal compared to many developing countries. There is a great potential for increasing the volume of steel in construction, especially in the current development needs. Not using steel as an alternative construction material and not using it where it is economical is a heavy loss for the country. Use of composite material is of particular interest, due to its significant potential in improving the overall performance through rather modest changes in manufacturing and constructional technologies. Steel concrete composite construction means the concrete slab is connected to the composite beam with the help of shear connectors so that they act as a single unit. In the present work, steel concrete composite (both full and half composite) with RCC options are considered for comparative study of seismic behavior of 10 multistoried commercial buildings (4-storied, 5-storied, 6-storied, 7-storied, 8-storied, 9-storied, 10-storied, 12-storied, 16-storied and 20-storied which is situated in earthquake zone V and for earthquake loading, the provisions of IS:1893 (Part1)-2002 is considered. For modeling of composite and RCC structures, SAP2000 software is used. Steel-concrete composite construction system is an efficient, economical and innovative method for seismic resistance of multi storied buildings. Equivalent static method of seismic analysis is used in the analysis of models. Comparison of parameters like time period, axial force, shear force, bending moment, deflection, storey drifts, base shear, storey stiffness is done for full composite (beam-column both composite), half composite (column composite) and RCC structures. The results are compared and found that composite structure is better in several aspects.

The usage of the fiber reinforced plastic (FRP) in marine applications offers ability to orient fiber strength, ability to mold complex shapes, low maintenance and flexibility. The most common reinforcement material in marine applications is E-glass fiber. Composite sandwich panels with FRP faces and low density foam cores have become the best choice for small craft applications. The U.S Navy is using honeycomb sandwich bulkheads to reduce the ship weight above the waterline. Composites will play their role in marine applications due to their lightness, strength, durability and ease of production. It is expected that especially FRP composites will endure their life for many years from now on in the construction of boat building.

Present-day construction is greatly influenced by steel-concrete column composites. Steel-concrete composite gained extensive attention around the globe, which made steel-concrete composite utilization in construction more attractive than conventional reinforced cement concrete design. Different architectural culture has introduced inexhaustible diversification of different columns. One of the most widely used is concrete-encased columns. These columns are those in which steel is encased in reinforced concrete. Combining these two materials leads to less cross-sectional area, high rigidity, and improved lateral resistance. However, some construction difficulties are evident. A comprehensive overview of the state of the art of evolution of composite columns in building structures based on experimental numerical and analytical studies is emphasized in the paper. Moreover, replacing concrete with various materials such as cement aggregates, limestones, fly ash, and industrial waste is suggested to deal with the high cost of the construction.

Abstract Office and retail interior fittings have a relatively short service life of 5-7 years. In this context, composite materials are often used, hindering possibilities of reuse or recycling. This research explores novel bio-composite materials and subsequently a construction method for CO2-neutral, circular interior fittings for office spaces. Based on the potential of fungal mycelium as a rapidly renewable, regenerative, affordable, low-carbon building material, bio-composite construction methods are explored in conjunction with timber-based additive manufacturing using continuous fibres. As mycelium has potentially excellent sound-absorbing properties but low load-bearing capacity, composite construction of timber veneer and mycelium allows to increase the structural capabilities of resulting components, while relying entirely on bio-based value chains. We describe the production process as well as the material development, including robotically aided processes for additive manufacturing of veneer reinforcement grids and compatibility studies of different mycelial species and substrates, and their bonding capabilities with veneer. We further present initial results on the mechanical characterization of the composite material, and its comparison to conventional mycelium composites. Minimal structural, acoustic, and functional requirements for different interior fitting elements are studied and compared to the characteristics of the proposed composite, highlighting the range of applications of the presented wood-mycelium composites.

Through crushing, screening and grinding, abandoned mortar power can be used as a mineral admixture to replace cement. Physical-activated, alkali-activated and composite-activated have been researched on activity of abandoned mortar power. Mechanical properties and microstructure were tested by compressive strength, flexural strength, XRD, TG-DSC-DTC and SEM. The results show that: Mechanical grinding and activator can significantly improve the activity of mortar power. Stimulating effect of single activator was not obvious. Composite activator has better effect than signal activator and it can promote further hydration of cement. The mortar which is stimulated by composited activator had higher strength than mortar with single activator. It can be seen from micro-test, the mortar with composite activator had more ettringite and other hydration products, having compact structure.

The main goal of the paper is to calculate the heat conductivity for three experimental hemp–lime composites used for structural construction purposes with the use of the experimental stand inside two compartments. Due to current construction trends, we are constantly searching for eco-friendly materials that have a low carbon footprint. This is the case of the analyzed material, and additional thermographic heat distribution inside the material during a fire resistance test proves that it is also a perfect insulation material, which could be applied in addition of popular isolating materials. This paper presents the results of certain hemp–lime composite studies and the potential for using hemp–lime composite for the structural construction industry. Hemp–lime composite heat transfer coefficient, fire resistance, and bulk density properties are compared to those of other commonly used construction materials. The obtained results show that the material together with supporting beams made of other biodegradable materials can be the perfect alternative for other commonly used construction materials.

The structure is combined of few layers; external layers are made of corrosive resistance material with dielectric behavior while the internal part of the composite is made of electrically conductive material with high conductive and mechanical properties. Conductive properties of each layer have been measured as well as their mechanical properties and structure. Also, the features of the joints between layers in terms of structure and properties were defined. More than that, varieties of mixtures and their possible usage are considered. Conductive properties of composite materials and ways of their adjustment have been described as well. For the first time, the measuring scheme of conductive properties for each layer was offered and heat shrinkable tubes and copper electrodes were used for it. Efficiency of modified composites and its behavior when electrical current applied can be measured by using the scheme.

Nowadays, the construction of cement composite using 3D printers is considered one of the most promising methods of automation of building processes. However, the compositions of cement composites have several disadvantages, such as high cost, short workability and etc. It has been suggested that clay soil as an additive will help to solve these problems partially. The aim of the work is development the cement compositions with clay soil, for use in 3D printers to construction. The composite consists of cement paste with clay soil and additives. To study printability of a composite the rheological properties in a fresh state were studied. The study of the rheological properties of composites was carried out using a flow table test for mortar. The key factor for determining the suitability of the composite for printing was accepted the diameter of the cone after shaking. The test results showed the possibility of replacing cement paste with clay soil up to 25% which leads to a reduction in the cost and an increase in printability with a slight decrease in the strength of the obtained material to 7%. Utilizing of soil from the construction site provides maximum economic efficiency of the material application.

Fiber-reinforced mycelium (FRM) composites offer an innovative and sustainable approach to construction materials for architectural structures. Mycelium, the root structure of fungi, can be combined with various natural fibers (NF) to create a strong and lightweight material with environmental benefits. Incorporating NF like hemp, jute, or bamboo into the mycelium matrix enhances mechanical properties. This combination results in a composite that boasts enhanced strength, flexibility, and durability. Natural FRM composites offer sustainability through the utilization of agricultural waste, reducing the carbon footprint compared to conventional construction materials. Additionally, the lightweight yet strong nature of the resulting material makes it versatile for various construction applications, while its inherent insulation properties contribute to improved energy efficiency in buildings. Developing and adopting natural FRM composites showcases a promising step towards sustainable and eco-friendly construction materials. Ongoing research and collaboration between scientists, engineers, and the construction industry will likely lead to further improvements and expanded applications. This article provides a comprehensive analysis of the current research and applications of natural FRM composites for innovative and sustainable construction materials. Additionally, the paper reviews the mechanical properties and potential impacts of these natural FRM composites in the context of sustainable architectural construction practices. Recently, the applicability of mycelium-based materials has extended beyond their original domains of biology and mycology to architecture.

Natural fiber-reinforced composites are becoming a growing trend because of their affordability, sustainability, abundant natural source, and minimal environmental effect. It has also shown to be an effective replacement of synthetic fiber, particularly in the transportation and construction sectors as ceiling, paneling, partition etc. In this study the jute fiber (Hessian Cloth) reinforced (10% to 50% fiber content by weight) Polypropylene (PP) and Polyethylene (PE) composite were made by compression molding technique to understand the effect of fiber loading on mechanical properties of two different thermoplastic composite materials. For jute fabric-reinforced thermoplastic composites, it was discovered that with 30 % fiber loading with PP and PE yielded the best results. It was found that the mechanical properties of the composites enhanced significantly with 30 % fiber content with PP and PE thermoplastic matrixes in contrast to 10% and 20% fiber content composites. However, increasing the fiber content over 30%, dramatically decrease the mechanical properties of the composite samples. The relationship between Tensile Strength (TS), Bending Strength (BS), Impact Strength (IS) and Tensile Modulus (TM), Bending Modulus (BM) was examined, along with water resistance properties for both composites. Additionally, the jute-reinforced polypropylene (PP) composite showed superior mechanical capabilities compared to the jute-polyethylene (PE) composite. This suggests that it could be a suitable replacement for the toy manufacturing, home or garden furniture, automotive and interior construction industries in the future.

Composite construction produces stiffer, stronger sections by the efficient use of both steel and concrete. The desirable composite action, however, is not possible unless adequate shear transfer at the steel member-concrete interface is provided. During the last several decades, several types of shear connectors have been developed to insure this transfer of shear; the most common connector is currently the headed stud. This type of shear connector requires a certain amount of slip to occur before composite action can be established. A new type of shear connector for composite construction, called the Perfobond shear connector has recently been developed to eliminate some of the problems and difficulties associated with standard shear studs. A coordinated experimental and analytical study was undertaken to further examine the behavior of composite members utilizing the Perfobond shear connectors, and to develop a reasonably simple, yet reliable design equation.

The paper describes use of hemp boon as a natural organic filler for building materials, especially concrete designed as heat - insulating filler material around the load-bearing structure of wooden buildings. In constructions, hemp has been used in the form of mats made of hemp fiber, with the addition of bonding bicomponent fibers and soda solution for protection against burning and rots. Mats are formed by pneumatic fleece, they are subsequently thermally treated and then cut to the desired dimensions. Calcium-hemp building material is a revolutionary construction and thermal insulating material which can be used for building the entire building, bricks or other insulation are not necessary. The trend is spreading across Europe from France, where the mixture of boon and lime was used in the 16thand 17thcenturies for the construction of timber-framed houses. Although there are hundreds of buildings made from hempcrete in Europe, its use in our country develops very slowly. Concrete is a mixture of hemp boon, lime hydrate, cement and water. It is a recyclable material that offers high thermal and sound insulation. The biggest advantage is undoubtedly the speed of construction, namely hemp concrete hardens very quickly.

Due to the increasing concern about the environment and depleting conventional materials, a lot of research is going on in the field of material science to develop environment friendly materials, and to improve the recycling and reusing of waste materials. Composites are material providing possibilities to reach these targets. In this experimental study, the possibilities and potential in the utilization of mixed waste from recycling in the manufacturing of epoxy composites are studied. The studied properties are flexural properties, i.e. flexural strength and flexural modulus, and hardness as mechanical properties, and water absorption and thickness swelling as physical properties. Element analysis was used to determine the composition of construction and demolition waste used in manufacturing. The analysis revealed a large proportion of mineral elements with high hardness. Consequently, this had a clear impact on the hardness of the composite. The flexural properties were found to be on a reasonable level. The waste-epoxy composite showed a low uptake of water due to the minor content of hydrophilic materials present in the composite.

Fiber-reinforced polymer (FRP) composites have been used more often over the past decade than before in new construction as well as in repair of deteriorated bridges. Many of these bridges are on low-volume roads, where they receive very little attention. It is imperative that new bridge construction or repair be long lasting, nearly maintenance free, and as economical as possible. Relative to those factors, FRP composite bridges have been found to be structurally adequate and feasible because of their reduced maintenance cost and limited environmental impact (i.e., no harmful chemicals leaching into the atmosphere with longer service life). In West Virginia, 23 FRP composite bridges have been constructed, among which 18 are built on low-volume roads that have an average daily traffic (ADT) of less than 1,000, including 7 with ADT less than 400. General FRP composite bridge geometry and preliminary field responses are presented as are some of the preliminary construction specifications and cost data of FRP composite bridges built on low-volume roads in West Virginia

Due to its environmental acceptability, technological feasibility, and economic viability, natural fiber-reinforced composite exhibits many potential engineering applications. However, the production and recycling of natural fibers are expensive. Researchers are now comparing natural fiber-reinforced composites with synthetic composites to determine the best materials, especially for construction and automotive engineering applications. This review paper focuses on natural fiber reinforced epoxy composites’ physical, mechanical, and thermal characteristics. These properties are critical for the effective design and use of composite materials such as construction and automotive applications. This review begins with a background of epoxy and natural fibers.

Abstract Fine aggregates of construction waste and fly ash were selected as additives to modify the characteristics of Shanghai clayey soil as a composite. The laboratory tests on consistency index, maximum dry density, and unconfined compressive strength were carried out mainly for the purpose of comparing the modifying effect on the composite from fine aggregates of construction waste with that from fly ash. It is mainly concluded from test results that the liquid and plastic limit of the composites increase with the content of two additives. But their maximum dry density all decreases with the additive content. However, fine aggregates of construction waste can increase the optimum water content of the composites, while fly ash on the contrary. Finally, although the two additive all can increase the unconfined compressive strength of composites, fly ash has better effect. The current conclusions are also compared with previous studies, which indicates that the current research results are not completely the same as those from other researchers.

Research has demonstrated that the formation of composites of titanium dioxide (TiO2) with silver phosphate (Ag3PO4) through the construction of heterojunctions can expand its light absorption range and suppress the recombination of photogenerated electron–hole pairs, thereby improving the photocatalytic performance. However, this method offers only limited performance improvements, and the composite photocatalysts are costly due to the expensive Ag3PO4. In this study, Ti3C2 MXene, which has good hydrophilicity and excellent electrical conductivity, is first used to form Schottky junction composites with bronze TiO2 (TiO2(B)) via electrostatic self-assembly. Then, Ag3PO4 quantum dots were further formed on the surface of the TiO2(B)/Ti3C2 MXene by in situ self-growth, and Ag3PO4 formed heterojunctions and Schottky junctions with TiO2(B) and Ti3C2 MXene, respectively. Finally, a ternary composite photocatalyst TiO2(B)/Ti3C2 MXene/Ag3PO4 was jointly constructed by these functional junctions. Under the synergistic effect of these functional junctions, the mobility and fast separation performance of photogenerated electron–hole pairs of the composite photocatalyst were significantly improved, the recombination of photogenerated electron–hole pairs was effectively suppressed, and the light absorption performance was enhanced. As a result, the composite photocatalyst exhibited excellent photocatalytic performances.

Building construction contributes a significant portion to the global consumption of energy and greenhouse gas (GHG) emissions, and decarbonization has become one of the main targets. This has turned much attention to renewable materials, particularly timber construction. Wood is a natural composite, and it causes challenges in its natural state due to its mechanical properties and functionality, which has constrained its use in construction. Laminating wood sections into glue-laminated (glulam) and cross-laminated timber (CLT) components overcomes limitations in dimensions and inconsistencies in its properties. We went beyond these technologies and explored the potential of combining timber of the radiata pine species with synthetic fibers, aiming for hybrid natural–synthetic composite beams. This research illustrated various reinforcement mechanisms and analyzed their structural properties. The results from the experiments showed that carbon fiber-reinforced timber composites have up to 49% additional increase in load-bearing capacity compared to unreinforced beams. An identical amount of strain required less stress, and the composite portrayed a metal-like ductility property, a characteristic referred to as pseudo-ductility. It reduces the material consumption in beams through a more efficient use of materials, particularly around compression areas before tensile rupture. The resulting composites are sustainable yet structurally capable, contributing to the reduction in CO2 emissions in timber construction systems.

The most popular materials for lightweight constructions, including building and aircraft structures, industrial, military, and aerospace technology, are armored composites. Composites made of carbon fiber are typically employed in lightweight applications. The ANSYS program was used to produce four mathematical models. Steel is used in the construction of the first and second versions whereas composite materials are used in the third and fourth variants. To find all the deformations, stresses, and strains that appear on the four models, as well as to calculate the weights of those four structures and compare them, these four models were tested with the ANSYS 15.0 program to obtain equal deformation resistance for all models under the influence of different loads. The results show that the composite models had lower strains, stresses, and deformations than the steel models. Among other results, it was discovered that the weight of the third model made of composite materials decreased by (32.72%) compared to the steel-based first model, and after doing the necessary calculations and assessing the results, the fourth model made of composite materials' weight was reduced by (19.21%) when compared to the second model made of steel.
