this article discusses some new modern technologies in the construction of highways. The paper analyzes the use of such innovations as: various modifiers added to bitumen; advanced technologies of engineering surveys and computer-aided design of highways; geosynthetic materials for reinforcing the roadbed and asphalt concrete pavement; PBB; bituminous polymer road belts; geotextile; foam-glass rubble; rubber crumb. The advantages of using innovations in road construction are highlighted. Obstacles to the use of certain technologies are noted, taking into account the Russian reality.
The author concludes that the use of innovative materials becomes economically justified at the stage of construction and subsequent operation of the road surface. New technologies can not only improve the quality of roads, but also improve road safety.
Innovations lead to progressive changes and ensure the dynamic development of the construction industry, primarily by reducing the cost and timing of construction, improving the quality of constructed facilities, and improving the comfort of living and operation.
The paper discusses classical methods for the design works of the foundation and the GM made a review of modern structures and technologies on their device. In order to assess the possibility of using linear calculation for sheet piling fences, deep pit modeling was performed in the SCAD and PLAXIS software systems.
The results of the work are the following conclusions:
1. the method of increasing the efficiency of technologies at the device walling of the pit is proposed;
2. a finite element model of soil and GM collaboration was created.
To evaluate the effectiveness of the options, we used decision-making methods based on optimization criteria, taking into account the degree of risks involved in the work.
It is established that the necessary factor is the geotechnical support of technological impacts, which allows monitoring of works on the degree of safety and impact on highways.

The paper presents data on the volume of materials consumed by builders and the carbon dioxide emissions that occur during this process. The reasons for the formation and volume of construction debris are considered. Recycling technologies currently used in the demolition of buildings are associated with crushing. The resulting concrete mix is used only for filling low-level earthworks due to the rapid carbonation of concrete surfaces. The scrap metal formed during crushing is used for remelting, polluting the atmosphere and requiring a large amount of energy. It is proved that due to the low economic and environmental efficiency, this method of recycling is a dead end. Studies have found that the constant increase in the strength of concrete and the absence of a decrease in the strength characteristics of reinforcing steels, stone materials, bricks, which are operated for a long time in favorable temperature and humidity conditions, allows them to be reused. General approaches have been developed that require changes in the existing technologies for the renovation of urban areas, the demolition of individual buildings and structures that currently exist. To reduce CO2 emissions and construction debris, it is enough to increase the volume of gentrification, reconstruction, major repairs, and re-profiling of the existing residential and industrial stock. When demolishing buildings, it is necessary to abandon the method of collapse of building structures with their further fragmentation. The method of piecemeal dismantling with repeated use of materials, products and structures (after determining their strength indicators by specialists), allows you to dramatically reduce the problems of construction debris and carbon dioxide emissions.

The article is devoted to the analysis of the current state and prospects of development of digital technologies in construction. The fundamental concepts of digital economy, digital production and digital technologies are introduced; a peculiar "evolution" of the design process in construction is described (transition from so-called "paper-based" technologies to computer aided design systems and further to information modeling of construction objects). Contemporary achievements of mathematical and computer modeling of loads and impacts, contemporary achievements and problems of mathematical (numerical) modeling of the stress-strain state, dynamics and stability at the basic and special combinations ofloads and impacts at significant stages oflife cycle of construction object are specified. Digital technologies in experimental and field studies are considered, the interrelation with mathematical modeling is shown, digital technologies in production of materials, products and structures are presented, the brief and substantial analysis of development of computer material science is given. Among the very topical issues raised in the article we should also highlight BIM - a fundamentally new approach in architectural and construction design, which includes creation of a computer model of a new building (structure), which carries all the information about the future of the object and is an instrument of control over its life cycle. Building Information Model is, in essence, a reflection of the ideas of the digital economy in construction and digital technology in the construction economy. The article also explains the concept of so-called "smart" home, "smart" district, "smart" city, "smart" region and "smart" country, which are normally used by professionals in terms of current realities,long-term and medium-term prospects. Finally, the expediency of development of design codes in the field of information technologies is assessed.

The modern stage of shipbuilding industry development is characterized by an intense competition and the beginning of introduction of new materials and effective welding technologies, which change the appearance of this quite conservative field, at leading global shipbuilding enterprises. In particular, the application of laser technologies during ship construction decreases the cost of hull manufacturing by 30%, increases the production capacity by 10%, and reduces welding deformations by 30% compared to traditional welding methods. The application of composite materials for ship construction allows decreasing the ship weight by 10%, which leads to 1-7% decrease in fuel consumption, reduction of polluting emissions and significant saving of expenditures. Adhesion-bonded joints become more frequently used in shipbuilding, as they off er a possibility of joining different materials along with the advantages brought by the adhesion process itself, being reliable, cost-efficient and ensuring easy maintenance and repair.

As the size and scale of construction projects increase, inefficiencies related to the manual operations about field data in current tracking systems are becoming an important issue. While emerging wireless technologies are providing a feasible vision of ubiquitous computing and sensor networks applicable to the large-scale construction industry, it has become even harder to select a suitable technology for tracking construction materials because of the differing functionalities, capabilities, and scope of application of the specific technology. This research proposes a multi-criteria decision-making model that leverages the decision process in choosing various wireless technologies available on the market. To justify the selection of a specific technology, a fuzzy method was adopted to provide an appropriate way to decide among five alternatives (e.g., RFID, GPS, Wi-Fi, Zigbee, and UWB). Fuzzy ranking was obtained from the aggregated fuzzy appropriate index (FAI) based on a person's point of view (optimist, pessimist, or neutral). The results showed that Wi-Fi might be a suitable solution for optimists and neutral persons, but UWB might be the better alternative for pessimists. The results of this research may assist construction engineers in applying reasonable decision-making procedures in a fuzzy environment such as construction sites, and rank the relative importance of the various criteria and alternatives specified in this research. Santrauka Augant statybos projektų mastui, rankinis dabartinių stebejimo sistemų duomenų apdorojimo neefektyvumas tampa svarbia problema. Nors naujos belaidžio ryšio technologijos gali sudaryti galimybę įvesti visur prieinamus kompiuterinius ir jutiklių tinklus, naudojamus plataus masto statybos pramonėje, tampa vis sudėtingiau pasirinkti tinkamas technologijas statybinėms medžiagoms stebėti, nes kiekviena technologija atlieka skirtingas funkcijas, skiriasi jų galimybės ir taikymo apimtis. Šiame tyrime siūlomas daugiakriterinis sprendimų priėmimo modelis, kuris, sprendimų priėmimo procesą pasirenkant rinkoje, siūlomas belaidžio ryšio technologijas išskaido į atskirus lygius. Siekiant pagrįsti tam tikros technologijos pasirinkimą, buvo pritaikytas neapibrežtųjų aibių metodas, pasirenkant geriausią technologiją iš penkių alternatyvų (t. y. RFID, GPS, Wi-Fi, Zigbee ir UWB technologijų). Neapibrežtumo rangas buvo gautas taikant agreguotą neapibrežtumo tinkamumo indeksą (FAI), atsižvelgiant į asmens požiūrį (optimistinis, pesimistinis ar neutralus). Gauti rezultatai parodė, kad Wi-Fi technologija yra tinkama optimistams ir neutraliems asmenims, o UWB technologija būtų geresnė alternatyva pesimistams. Šio tyrimo rezultatai gali padėti statybos inžinieriams priimti pagrįstus sprendimus neapibrėžtoje aplinkoje, tokioje kaip statybos aikštelės, ir suranguoti pagal svarbą įvairius kriterijus bei aptartas šiame tyrime alternatyvas.

The sustainability of transportation infrastructure depends on the adoption of new construction materials and technologies that can potentially improve performance and productivity. However, most agencies would like to evaluate these new materials and technologies at both the project and network levels before replacing the traditional ones. It also remains a challenge to reliably estimate the costs and lifetime performance of new construction materials and technologies because of limited implementation data. To address these issues, this paper presents a comprehensive bottom-up methodology based on Life Cycle Cost Analysis (LCCA) to integrate project- and network-level analysis that can fast-track the acceptance of new materials or technologies. Hypothesized improvement rates are applied to the deterioration functions of existing materials to represent the expected improved performance of a new material compared with a conventional material with relatively similar characteristics. This new approach with stochastic treatment allows us to probabilistically evaluate new materials with limited data for their future performance. Feasible maintenance and rehabilitation schedules are found for each facility at the project level and near-optimal investment strategies are identified at the network level by using a metaheuristic evolutionary algorithm while satisfying network-wide constraints. This provides an effective solution to many issues that have not been fully addressed in the past, including the trade-off between multiple objectives, effects of time, uncertainty, and outcome interpretation. A hypothetical bridge deck system from New Jersey’s bridge inventory database is used to demonstrate the applicability of the proposed methodology in constructing a planning and management decision-support procedure.

Technological processes in all branches of production are maximally automated in the world, this also applies to construction. The main driver of automation of construction processes is 3D printing technology. The first driver was the invention of stereolithography technology, which was discovered in 1986 by American engineer Chuck Hull. The article describes the process of 3D printing technology, using different materials and printing principles. The main 3D printing includes the application of the material in layers at high temperatures (for small plastic products) and layer by layer of concrete mix and geopolymer concrete when printing houses. The first to start using 3D printers in construction was the Chinese company Winsun. Also considered are building structures (buildings and structures) that were built using 3D printers, compared to their technical and economic indicators. The positive and negative aspects of the use of 3D printers in construction are studied. In the future, it is planned to study plastics of ABS and PLA brands to create structural building elements with the subsequent use of these elements in construction.

The article presents an overview of modern plastics for use in rail vehicles. The analysis of plastics and composites in the constructional aspect was analyzed. The trends in the development of polymer materials, technologies and constructions used in the manufacture of vehicles, on the one hand, are determined by the technical and economic requirements of industry and, on the other, by the continued emphasis on reducing fuel consumption and CO2 emissions. Further development will be subject to pre-impregnation techniques, particularly in the form of different types of reinforcement. Full use of the advantages of reinforced polymer materials in vehicle production will only be achieved when further optimization of the resin properties and development of automation will result in the widespread use of composite components in series production. Observing the trends and pace of development, it is possible to predict that there are still restrictions on the use of polymeric materials in the transport sector, such as relatively high prices, technological constraints and the hindering automation of large-scale production. Modern construction and material solutions, in particular those using reinforced plastics, are primarily designed to reduce vehicle weight and have better noise and vibration damping properties. Rail vehicles are becoming more environmentally friendly at the time and travel comfort is higher.

The article at hand follows the understanding that future cities cannot be built the same way as existing ones, inducing a radical paradigm shift in how we produce and use materials for the construction of our habitat in the 21st century. In search of a methodology for an integrated, holistic, and interdisciplinary development of such new materials and construction technologies, the chair of Sustainable Construction at KIT Karlsruhe proposes the concept of “prototypological” research. Coined through joining the terms “prototype” and “typology”, prototypology represents a full-scale application, that is an experiment and proof in itself to effectively and holistically discover all connected aspects and address unknowns of a specific question, yet at the same time is part of a bigger and systematic test series of such different typologies with similar characteristics, yet varying parameters. The second part of the article applies this method to the research on mycelium-bound building materials, and specifically to the four prototypologies MycoTree, UMAR, Rumah Tambah, and Futurium. The conclusion aims to place the results into the bigger research context, calling for a new type of architectural research.

Construction Biotechnology is a new scientific and engineering discipline that has been developing exponentially during the last decade. The main directions of this discipline are 1- the selection of adequate microorganisms, 2- development of micro-processed construction bioprocesses as well as 3- the development of new biotechnologies to produce construction biomaterials. Products resulting in construction biotechnologies are low-cost, sustainable, and environmentally friendly microbial biocements for the improvement of the construction terrain. The bioagents used in construction biotechnologies are pure or enrichment cultures of native microorganisms or microorganisms isolated and activated from the soil. Biotechnologically produced construction materials and microbial mediated construction technologies have many advantages compared to conventional construction materials and processes. The current technological landscape offers an objective vision and perspective of how microbes are used in the construction industry as additives for cement and concrete so that these new technologies be used in different provinces of Ecuador. In that sense, the current situation of cement and concrete production in Ecuador is briefly described to have an overview of the applicability of the new methods based on biogenic materials and the environmental advantages of the creation of construction biomaterials over conventional production.

Concrete materials and paving technologies have evolved considerably during the past century. However, testing technologies for concrete during construction have not kept pace. Some of the tests that are routinely used are not necessarily performance indicators and some are not made in real time. Seven new technologies are presented that are simple, real-time, field implementable, and economical and in many cases are performance indicators. Although some of these technologies could be used during the mixture design stage, others could be used during construction and some for both purposes. These technologies can be used to supplement or, in some cases, to replace the traditional tests for paving concrete. The discussion focuses on three items: ( a) traditional tests for paving concrete, ( b) new tests and technologies that could be used to supplement or replace the traditional tests, and ( c) suggested future specifications. Data collected by the FHWA Mobile Concrete Laboratory from its technology implementation efforts are presented to support the narrative on the benefits of these new technologies.

A person spends most of his life in rooms built from various building materials; therefore, the optimization of the human environment is an important and complex task that requires interdisciplinary approaches. Within the framework of the new theory of geomimetics in the building science of materials, the concepts of technogenic metasomatism, the affinity of microstructures, and the possibilities of creating composites that respond to operational loads and can self-heal defects have been created. The article aims to introduce the basic principles of the science of geomimetics in terms of the design and synthesis of building materials. The study’s novelty lies in the concept of technogenic metasomatism and the affinity of microstructures developed by the authors. Novel technologies have been proposed to produce a wide range of composite binders (including waterproof and frost-resistant gypsum binders) using novel forms of source materials with high free internal energy. The affinity microstructures for anisotropic materials have been formulated, which involves the design of multilayered composites and the repair of compounds at three levels (nano-, micro-, macro-). The proposed theory of technogenic metasomatism in the building science of materials represents an evolutionary stage for composites that are categorized by their adaptation to evolving circumstances in the operation of buildings and structures. Materials for three-dimensional additive technologies in construction are proposed, and examples of these can be found in nature. Different ways of applying our concept for the design of building materials in future works are proposed.

This paper presents an ongoing research project about the development of the materials and fabrication techniques for a fundamentally new class of architectural composite. This type of composite, which is a representative example of an even broader class of smart architectural material, has the potential to change the design and function of an architectural structure or living environment. As of today, this kind of composite does not exist. Once completed, this will be the first technology on its own. We believe this study will lay the fundamental groundwork for a new paradigm in surface engineering that may be of considerable significance in architecture, building and construction industry, and materials science.

Purpose: The aim of the paper is to identify effective ways of architectural form making of public facilities using an ecological approach. This is due to a new role of architecture in the urban sustainable development through the creation of aesthetically attractive and functional comfortable and safe environment. A special attention is paid to economic efficiency of objects, namely cost reduction in building construction and operation. This goal can be achieved through the improvement of design and construction technologies, development of the construction material industry, and interdisciplinary approach to the problem solution which implies the collaboration of specialists. Methodology/approach: Analytical, synergetic and inductive approaches are used in these studies. Based on the identification of particular cases of the new approach to the application of living nature in architecture and construction and their analysis and systematization, an algorithm of creating architectural objects is developed using natural technologies. The fields of their application are indicated within the architectural theory and practice. Form making experiments are carried out using natural technologies utilized by foreign specialists. Findings: Natural technologies can be systemized in the following way: – a living being as a prototype of an architectural object (external form, architectural bionics); – construction technology used by a living being as a prototype of building technologies in architecture (principle of space organization and structure formation); – a living being as a builder of architectural objects (e.g. use of bacteria as a building material); – a living being as a source of building material (objects produced by living beings, such as shells, chitin, silk thread, etc.). It is found that this approach is being intensively developed by foreign architects and designers jointly with other specialists (engineers, biologists, etc.), but has no spheres of application as well as related centers in Russia. Results: Natural technologies are very important for the transition to a model of sustainable urban development, since their use improves the ecological situation, provides efficient use of natural resources and reduces construction costs. A research group should be created for studying the foreign experience in using natural technologies for the development of research program on implementing this approach in Russia. Practical implications: Research results can be readily used for subsequent studies on similar or related topics; in the academic process for training architects; in real design of ecoarchitectural creative spaces and objects, which will positively affect the development of green economy in Russia. This approach can be applied in different regions and climatic zones of the world with its adaptation to local conditions, because it is a universal design method with mandatory application of the creative approach. Originality/value: The originality of research lies in the architectural typology modification connected with form making, planning and design concepts. Systematization of local knowledge and experiments is provided by construction materials and technologies. Theorization of the new pre-design and design methods can be identified as a natural technology approach.

Crystalline silicon forms the basis of just about all computing technologies on the planet, in the form of microelectronics. An enormous amount of research infrastructure and knowledge has been developed over the past half-century to construct complex functional microelectronic structures in silicon. As a result, it is highly probable that silicon will remain central to computing and related technologies as a platform for integration of, for instance, molecular electronics, sensing elements and micro- and nanoelectromechanical systems. Porous nanocrystalline silicon is a fascinating variant of the same single crystal silicon wafers used to make computer chips. Its synthesis, a straightforward electrochemical, chemical or photochemical etch, is compatible with existing silicon-based fabrication techniques. Porous silicon literally adds an entirely new dimension to the realm of silicon-based technologies as it has a complex, three-dimensional architecture made up of silicon nanoparticles, nanowires, and channel structures. The intrinsic material is photoluminescent at room temperature in the visible region due to quantum confinement effects, and thus provides an optical element to electronic applications. Our group has been developing new organic surface reactions on porous and nanocrystalline silicon to tailor it for a myriad of applications, including molecular electronics and sensing. Integration of organic and biological molecules with porous silicon is critical to harness the properties of this material. The construction and use of complex, hierarchical molecular synthetic strategies on porous silicon will be described.

Purpose – The purpose of this paper is to evaluate the risks of building defects associated with rapid advancement of “green” construction technologies. It identifies the methods adopted by the sector for the determination of pre-construction defects that are framed within the context of, traditional; scientific; and professional design approaches. These are critically evaluated and utilised in attempts to mitigate defects arising from diffusing low carbon construction innovations. Design/methodology/approach – The paper takes the form of an evaluative literature review. Polemic in orientation, the paper critically compares two periods of time associated with rapid advancement of innovation. The first, the post-Second World War housing boom is synonymous with a legacy of substandard buildings that in many cases rapidly deteriorated, requiring refurbishment or demolition shortly after construction. The second, is today’s “green” technology “shift” with its inherent uncertainty and increased risk of latent building defects and potential failure to deliver meaningful long-term performance. Central to this is an exploration of the drivers for innovation, and subsequent response, precautionary measures initiated, and the limitations of institutionalised systems to identify and mitigate defects. Similarities and differences between these historical periods frame a discussion around the theoretical approaches to defects and how these may be limited in contemporary low carbon construction. A conceptual framework is presented with the aim of enhancing the understanding for obviation of defects. Findings – Sufficient commonality exists between the periods to initiate a heightened vigilance in the identification, evaluation and ideally the obviation of defects. Design evaluation is not expressly or sufficiently defect focused. It appears that limited real change in the ability to identify defects has occurred since the post-war period and the ability to predict the performance of innovative systems and materials is therefore questionable. Attempts to appraise defects are still embedded in the three principle approaches: traditional; scientific; and professional design. Each of these systems have positive characteristics and address defect mitigation within constrains imposed by their very nature. However, they all fail to address the full spectrum of conditions and design and constructional complexities that lead to defects. The positive characteristics of each system need to be recognised and brought together in an holistic system that offers tangible advantages. Additionally, independent design professionals insufficiently emphasise the importance of defect identification and holistic evaluation of problems in design failure are influenced by their professional training and education. A silo-based mentality with fragmentation of professional responsibility debases the efficacy of defect identification, and failure to work in a meaningful, collaborative cross professional manner hinders the defect eradication process. Research limitations/implications – Whilst forming a meaningful contribution to stimulate debate, further investigation is required to tangibly establish integrated approaches to identify and obviate defects. Practical implications – The structured discussion and conclusions highlight areas of concern for industry practitioners, policy makers, regulators, industry researchers and academic researchers alike in addressing and realising a low carbon construction future. The lessons learned are not limited to a UK context and they have relevance internationally, particularly where rapid and significant growth is coupled with a need for carbon reduction and sustainable development such as the emerging economies in China, Brazil and India. Social implications – The carbon cost associated with addressing the consequences of emerging defects over time significantly jeopardises attempts to meet legally binding sustainability targets. This is a relatively new dimension and compounds the traditional economic and societal impacts of building failure. Clearly, blindly accepting this as “the cost of innovation without development” cannot be countenanced. Originality/value – Much research has been undertaken to evaluate post-construction defects. The protocols and inherent complexities associated with the determination of pre-construction defects have to date been largely neglected. This work attempts to rectify this situation.

Figure 9 is a summary of these basic processes. Many of these processes can be combined in any number of ways to create methods of manufacturing that are most advantageous to your product and business. Any process should be built on a combination of the best chemistry, energy transfer method, type of energy, material handling, and oven construction. These new processes should be tried and perfected on a trial basis before constructing a full equipment line. Some processes may best be achieved by putting multiple coaters, laminators, ovens, and other associated equipment in line. Most equipment manufacturers have test laboratory capabilities available so the equipment and chemistry can be developed together. It is also most essential to take into consideration any materials that will be emitted from the drying or curing process and their impact on employee safety and environmental regulations. Many times these problems can be avoided by a change in the chemistry.

AbstractIn the late nineteenth and early twentieth centuries, monumental Muslim tombs in India served as spaces for refashioning local religious and social identities. Elite patrons, technical overseers, and stoneworkers engaged with new technologies of construction at sites meant to reflect claims on the Muslim past. This article interrogates divergent class understandings of monumental Muslim tombs in colonial-era India. It compares the construction of monumental Islamic tombs in the states of Hyderabad, Bhopal, and Rampur—three Muslim-led ‘native states’, quasi-autonomous polities under colonial oversight. By the late nineteenth century, many native state patrons employed a new middle class of technical intermediary to oversee tomb construction. The rise of this class created new hierarchies within construction, with apprenticeship-trained master craftsmen increasingly marginalized from state narratives and aligned with stoneworkers and other labourers. While patrons and middle-class intermediaries argued that new technologies and materials should be used to ‘modernize’ construction, they portrayed technical change as divorced from the religious symbolism of tombs. In contrast, workers integrated the religious and the technical, positioning technologies of construction within narratives of Muslim practice. The article uses native state tombs to analyse how labourers adapted to technical demands, without necessarily adopting state ideologies.

Prefabrication technologies have been used in the building industry since the 19th century. The technologies vary from the innovative materials to novel techniques of construction and the prefabricated systems range from individual components to the entire structure. The major prefabrication technologies prevalent today include sandwich panel walling elements, hollow core slabs, light gauge steel frames as well as modular housing. Even though prefabrication technologies have been widely used in slabs, beams and columns, prefab foundation system is still a relatively new concept. The construction of foundation is the most important part of building process and hence a sound prefabricated foundation system is the need of the hour. In this paper, an attempt has been made for construction of a portable prefabricated reinforced concrete foundation which can be used in buildings up to three storeys.

The increase in energy prices resulted in the formation of new houses in the low-energy and passive standard. In particular, the development of wooden buildings in recent years has experienced a boom. More and more, their positive qualities come to the attention of potential investors. Thanks to this the new technologies of construction are still developed and the new wood-based materials tested. The continuous improvement of the thermal insulating materials and as well as technical equipment of buildings such as ventilation, heat recovery, solar and photovoltaic systems is recorded. All of these materials and technologies must follow the standards which tightened the thermal technical requirements. This led to the sophisticated compositions of individual structures and the use of better materials. Not always declared properties of the materials or construction planners are designed in accordance with the calculated values. In practice there is often ill-composition design of the construction or improper assembling of wooden parts which may result in an increase in thermal loss of the building, disturbed microclimate inside the building, but also negatively affecting the lives of individual structural units which implies that we should deal with these problems significantly.

Production of steel rolled products by using traditional metallurgical technologies are rather material- and energyintensive and its concentration at gigantic steel plants resulted in the increased expenses for transportation of raw materials and finished products. To solve the problems, a practice of comparatively small metallurgical plants (mini-mills) construction is becoming widespread in the world steel industry. The mini-mills include modern electric arc furnaces, ladle steel treatment facilities and steel continuous casters combined with continuous rolling mills. The review complied from materials of international conferences, taken place in 2015–2019. In the review achievements in equipment and technology of metal products at mini-mills development considered, as well as analysis of modern economical methods of steel coils presented. It was shown, that the methods of strips endless rolling, widely used already at industrial scale in several countries, enable producing rather thin hot-rolled strips from liquid steel. Universal casting-rolling aggregates (CRA) developed, by which high quality strips of rather wide assortment can be produced. For a mass production of rather thin (down to 0.8 mm) hot-rolled strips, which can in many applications substitute more expensive coldrolled ones, compact aggregates of endless casting-rolling are recommended, which provide the yield of up to 98%. Concepts of the CRA elaborated for production of steel strips of wide assortment, from ultrathin strips to thick (25 mm) ones. The concepts include application of thermomechanical treatment to increase the mechanical properties of the rolled products from various steels, including low-alloyed ones.

The construction sector constantly offers new products, more effective technologies and novel solutions aimed at improvement of the quality of human habitats and wider distribution of technologies. Currently, effective technologies that require less time and costs for production, installation and use are gaining greater significance. Among them are construction materials and technologies with increasingly popular sustainability features. Considering the above, the article offers a complex algorithm for assessing the deployment and distribution potential of a new technology/product. For this purpose, a multi-stage model of alternatives and criteria was suggested and an analytical multi-stage evaluation model has been designed. The practical example illustrates the assessment of micro environment using a combination of AHP (Analytic Hierarchy Process) and Permutation methods. The designed multi-criteria assessment model promotes accessibility of users to a technology, new product, a part of the product and a technological process.
