Resumen
Use of clay plasters in the exterior forces owners to conduct frequent maintenance of the plaster’s surface, which may be damaged by the weather. This paper describes partial results of the research, which strives to develop cost-efficient hydrophobic additives to increase service life of exterior clay plasters. We have chosen 7 hydrophobic materials and added them to the reference prefabricated plaster mixture. Samples of the enhanced plaster were tested to evaluate the additives’ impact on the overall mechanical, thermal and moisture characteristics of the plaster. Long-term testing of the best hydrophobic additives will follow to verify their properties in real buildings. Clay plasters play a significant role for the healthy indoor climate due to the influence on the stability of the indoor temperature and humidity.

Resumen
The Pre-Pottery Neolithic B (PPNB) site of Yiftahel, Israel, contains abundant plaster floors. We surveyed the states of preservation of the plasters using an infrared spectroscopic assay that characterizes the extent of disorder of the atoms in the calcite crystal lattice. We identified the 3 best-preserved plaster samples that had disorder signatures most similar to modern plaster. We then studied the surface layers, fine-grained matrices, and large aggregates of these samples using micromorphology, Fourier transform infrared (FTIR) microscopy, stable carbon and radiocarbon concentrations. Even though some of the plaster components have a geogenic appearance in micromorphology slides and in FTIR spectra, the 14C analyses show that all components were exposed to high temperatures and as a result were equilibrated with the 14C content of the atmosphere ∼10,000 yr ago. This implies that the plasters at Yiftahel were produced entirely from heat-altered calcite. We also show that these plasters have undergone significant diagenesis. The plaster component with the most disordered atomic signature, and hence the most similar in this respect to modern plaster, did indeed produce a 14C date close to the expected age.

Resumen
Several lime-based plasters with fine ground brick content are studied in this article. In the first plaster the ceramics was used as lime substitute while in the second one it was dosed as replacement of the silica sand, the substitution levels being 20% and 50%. Pure lime plaster was use as a reference. Experimental methods and results of measuring basic physical properties, pore characterization, mechanical properties and liquid water transport are described. The plasters with fine ground brick were characterized by improved material’s properties in a comparison with pure lime plaster.

Resumen
The objective of this work is to analyze the possibilities of reusing plastic waste of cables added in a plaster matrix. Firstly, the experimental process has allowed the physicochemical characterization of the raw material, plaster and plastic waste, consisting in elemental analysis, XRD and thermogravimetric analysis; Secondly, the performance of physicomechanical tests of the mixtures, Shore C hardness, absorption and resistance to flexion and compression. During the investigation, the water/plaster ratio of 0.8 was maintained, as well as the grain size of the plastic waste as it comes from the recycling factory (maximum 3 mm). On the contrary, the amount of added plastic waste has oscillated up to incorporate 50%, 60% and 70% over the weight of the plaster. In comparison to a reference sample, the obtained compounds are characterized by having a higher Shore C hardness, a lower absorption by capillarity and a decrease in their values of mechanical resistance. The addition of plastic waste to a plaster matrix can be considered as a possibility to obtain compounds of greater sustainability to be used in the field of sustainable construction.

Resumen
The paper deals with the use of lightweight porous aggregate, i.e. crushed expanded polystyrene package crumbs (EPSC) in the composition of thermo-insulating plaster. Its effectiveness is compared to that of spherical granules of expanded polystyrene – white coloured (EPS) and grey coloured (NEOPOR). The content of lightweight aggregate changed from 1.25 to 1.75 l/kg of dry mix. The investigation focused on properties of modified plaster, such as density, compressive strength, thermal conductivity and water vapour permeability. It was established that EPSC reduce density of plaster from 1350 to 530 kg/m3, improving such properties as thermal conductivity and water vapour permeability but decreasing compressive strength. In addition, the paper established the adhesion force of plaster (content of lightweight aggregate was 1.25 l/kg of dry mix) to ceramics, silicate and autoclaved aerated concrete masonry elements. The character of macrostructure of plaster was considered, as well as bonding with a coat of decorative paint. It was found that plaster with EPSC has similar properties to plasters with EPS and NEOPOR aggregates; however, in case of EPSC, the relative vapour resistance is better. The provided regression equations can be used for prediction of differently modified plasters.

Resumen
The article presents the results of analytical studies to establish the authentic component composition of the brick crumb plaster, which was used to furnish architectural monuments of the 10th – 12th centuries. In laboratory conditions, a number of experimental studies aimed at the production of brick crumb plaster according to the historical recipe were performed. However, a number of requirements were set for such plaster, according to which it must meet European and domestic requirements for drying renovation plasters. The peculiarity of such plasters is low compressive strength (1.5 – 5.0MPa), high porosity (>45 %) and a low coefficient of resistance to water vapour diffusion (12), which allows drying overmoistened walls and at the same time extracting salts from them and accumulating them in the pores of their volume. In the process of experimental research, the historical recipe of the plaster was slightly modified, which made it possible to obtain a plaster with the specified parameters. The performance of plastering works with a scientifically based recipe of brick crumb renovation plaster on an architectural monument in the city of Chernihiv gave a positive result with a decrease in salinity and humidity of the walls.

Resumen
Used as a predominant covering material in Central and Eastern Europe throughout the nineteenth and twentieth centuries, plaster’s malleable characteristics also enabled its efficient utilization as a material for imitating decorative features traditionally made from stone and marble. Instead of looking at plaster as an imitation material, this article proposes studying it as a material archive containing unintentionally preserved traces of the past that may include fragments of advertisements, graffiti, bullet holes, or virtually any inscription in plaster that would otherwise be bound to disappear. Plaster archeology is a mode of looking at plaster less as a conduit of architectural form and more as a material surface involving depth. As a discipline, plaster archeology entails a set of practices that allows one to attend to these surfaces, although not with the intention to save traces of the past from disappearance, but rather towards reconceptualizing plaster as a material in its own right that constantly transforms at the whims of human and climatic forces. By using two buildings located in the heart of Budapest’s seventh district as case studies, I will then demonstrate how the plaster archeologist views and examines façades. Finally, through an exploration of plaster’s characteristics and history, I argue for plaster archeology as a non-interventive mode of engaging with architectural surfaces.

Resumen
The structural performance of plastered straw bales under compressive loading is extremely important when considering the suitability of plastered straw bales as a construction material. Most currently available results do not investigate how different construction methods and practices can affect the strength of a plastered bale. The experiments discussed in this paper illustrate how the strength of the plaster, the thickness of the plaster and the orientation of the bale itself can affect the strength of the plastered bale. It was found that the bales plastered flat were 36% stronger than those plastered on edge. In addition it was found that although the plaster strength does affect the strength of the plastered bale, it does not have as significant an impact as the plaster thickness. It was also found that nearly all plastered bales tested had higher strengths than would be required in typical residential construction. The strengths were found to be in the same range as the values reported in the existing literature. The plastered bale modulus was found to be highly variable and un-predictable.

Resumen
Eco-friendly plasters offer several advantages, including sustainability, nontoxicity, and low cost. These plasters are made with sustainable materials, such as natural fibers and starches. These materials can have different mechanical properties compared to traditional plasters, which are made with gypsum and cement. Due to the increased attention being paid to environmental issues, efforts are still being made to switch out the conventional plaster of gypsum and cement for an eco-friendlier alternative to minimize toxicity, increase effectiveness, and lower cost. In this study, the effect of novel plaster behavior under pressure on mechanical properties was investigated. The plaster investigated was an eco-friendly carbon-free BSCO plaster. A range of experimental techniques were used, such as compression testing for confirmation using ANSYS 2023 R1 software, which set ergonomic and user-friendly standards as a minimum requirement, with the overarching goal of creating stronger, lighter, and more reasonably priced structures. The results showed that eco-friendly Bilateral Specialized Company (BSCO) plasters could have comparable mechanical properties to traditional plasters. Additionally, it is suggested that eco-friendly and carbon-free plasters can be a viable alternative to traditional plasters in a variety of applications. Researchers and civil engineers can both gain from this scientific paper’s potential to replace conventional stucco with an ecologically friendly alternative that has more effective mechanical qualities.

Resumen
The external plaster are currently the most common finish coat of buildings. The characteristic technological and chemical properties of plasters protect supporting structure against weather and temperature extremes. Quality of plaster is determined by its durability, which depends primarily on the quality of raw materials, the quality and porosity of the substrate, the temperature during application, concentration of carbon dioxide and humidity of the ambient air. The physical and chemical and biological degradation of plaster is caused due to weathering and exposure to aggressive substances of environment. The paper deals with the analysis of the causes of degradation (green facades) and the possibilities of remediation of biotic attack of plasters buildings with External Thermal Insulation Composite System (ETICS).

Resumen
Introducing Plaster is a degree work in textile design exploring the fusion of natural dyes and plaster, and how this can be applied as a textile design material. The outcome is presented as an experimental investigation, placed in the context of surface and material design. This study derived from a growing interest in how new materials can be implemented into the field of textile design using established textile techniques and methods. Natural dye, texture and flexibility where explored through the method of hands-on-experimentation. The study moved foreword by asking the question: “What happens if?”, and the findings have been analyzed and selected for further development. The final collection consists of five pieces made entirely from plaster, showing another approach to how textile techniques and methods can be developed and adapted to fit materials from another field, for instance: Plaster.

Resumen
Riksdagen (2020) har beslutat att Sveriges långsiktiga ekonomi ska styras successivt över från dagens konsumtionsekonomi mot en mer hållbar cirkulär ekonomi men ändå tyckts det enligt flera av de källor som har använts att det går alldeles för långsamt med övergången. Europeiska Kommissionen (2015) beskriver den cirkulära ekonomin som “… där värdet av produkter, material och resurser bibehålls i en ekonomi så länge som möjligt och där genereringen av avfall minimeras, som ett viktigt bidrag till EU:s ansträngningar för att utveckla en hållbar, låg koldioxid, resurseffektiv och konkurrenskraftig ekonomi”. Denna studien syftar till att studera framtida plaster utifrån en cirkulär ekonomi. Studien har tillämpat Rhetorical Structure Theory (RST) för en översiktlig men systematisk litteraturanalys med avsikt av att identifiera och kritiskt utvärdera forskning för att svara på en på förhand formulerad forskningsfråga. Granskningen föregicks därmed av en plan och inkluderar såväl kvalitativ som kvantitativ korpus forskning för att hitta, markera och räkna fall av begreppsanvändning och identifiera samband mellan begrepp, det vill säga de så kallade (s k) koherensrelationerna. En kvalitativ komparativ innehållsanalys mellan korpus har används mellan promemoria, utredningar tillsatta av regeringen och vetenskapliga artiklar. Med utgångspunkt i problembeskrivning är syftet med denna examensuppgift att utveckla kunskaper om plasters möjligheter och plats inom en framtida cirkulär ekonomi på basis av tidigare forskning. Genom en undersökning av existerande forskning är de huvudsakliga frågeställningarna för uppsatsen följande: - Vilka är framtidens plaster? - Har en bionedbrytbar plast en plats i samhället? - Hur ser framtidsutsikterna ut för biobaserade plaster och bionedbrytbara plaster? - Hur ser vårat samhälle ut i framtiden? Vi lämnade det gamla skänka och reparera samhället för ett köp och sälj samhälle och det finns ekonomiska teorier om vad som var de drivande incitamenten till det. Några av de krafter till förändringen/förändringarna var bland annat tillgången till billig arbetskraft, ny byggteknik för fabriker och lager och nya transportnät. På grund av dessa delar kunde man producera med köp och sälj teknologi och utöka mervärde. Nu idag när detta hotas börjar man prova andra produktionsformer. En cirkulär ekonomi med inslag av det gamla skänka och reparera samhället uppnås genom bland annat design där man designer för att öka livslängden för plastprodukter. På grund av den framtida plastens gränsöverskridande krävs det en kombination av nya styrmedel, beteendeförändringar och forskning för att hitta plastens plats i en cirkulär ekonomi. Resultaten bygger på analys av studiens litteraturkorpus vad beträffar information om plastens roll i en cirkulär- och bioekonomiskt samhälle där dess funktion har satts i relation till dess miljönytta och möjlighet till en plats i ett kretsloppssamhälle. Med ett ökat råoljepris och styrmedel i form av skattereduktionen och bidrag för verksamheter som vill blir mer hållbara möjliggörs en framtida cirkulär ekonomi. Genom design kan plastprodukter plockas bort från för ett mer hållbart samhälle. Syftet med rapporten har delvis kunnat beskrivas men på grund av komplexiteten av ämnet har det inte funnits några enkla svar till forskningsfrågorna då de beror på faktorer som går utanför studiens ramar.
In 2020, the Swedish Parliament passed a motion to move the national economic base from a linear toward a circular economy, but the transition may be moving too slowly. The European Commission (2015) describes a circular economy as ”… where the value of products, materials and resources is maintained in the economy for as long as possible, and the generation of waste minimized, as an essential contribution to the EU's efforts to develop a sustainable, low carbon, resource efficient and competitive economy”. This thesis aims to study future plastics from a circular economy perspective. The thesis has applied Rhetorical Structure Theory (RST) to produce systematic literature analysis with the intention of identifying and critically evaluating research to answer a specific research question. The review proceeded through a plan that included both qualitative and quantitative corpus research to find, mark and count instances of the use of concepts and identify conjunctions between them, that is so called coherence conjunctions. A qualitative comparative content analysis between corpora has been used involving independent scientific articles and reports from commissioned investigations appointed by the Swedish government. Based on the problem description, the purpose of this thesis is to develop knowledge about the possibilities and place of plastics in a future circular economy using previous research. Through a study of existing research, the main questions for the thesis are the following: - Plastics of the future? - A biodegradable plastic, does it play a role in the society? - What are the prospect for biobased plastics and biodegradable plastics? - What might our future society look like? We left the old donate and repair society for a buy and sell society and there are economic theories of to what was the driving incitements to that. One of which was accessibility of cheap labour, new construction technology for factories and warehouses and a new transport network that enabled factories to produce and transport goods within effectively and increase the surplus value of production (i.e. profit). Now today when global environmental challenges threaten the sustainability and profitability of this form of consumption economy efforts have emerged to uncover new production forms. A circular economy with elements of the old donate and repair society is one of them. It demands redesigning production to increase service life for plastic products. The future of plastic is at a crossroads that requires a combination of new policy instruments and changes in behaviour and research. The result is based on an analysis of the study’s literature corpus regarding information on plastics role in a circular- and bioeconomy society where its function is put in relation to its environmental benefits and its ability for a spot in a recycling society. Together with an increase in crude oil and policy instruments in the form of tax reductions and subsidies for commercial activities who want to become more sustainable it enables a future circular economy. The aim of this thesis has been fulfilled, but the complexity of the subject has led to unanswered research questions due to factors that lie somewhat outside the scope of the study.

Texto completo
Resumen
Plaster and compo are both materials used for cast architectural ornamentation. Preserving, repairing, and in-kind replacing cast architectural ornamentation is necessary to maintain the integrity of a space. Plaster and compo are visually and texturally very similar materials. Compo was invented to be a less costly substitute for plaster. Whereas the two materials are easily mistaken for one another, they are chemically quite different. The ingredients and methods used to create the two separate materials exemplify this difference. Understanding the differences is key to successfully preserving the ornaments and, thus, the spaces in which they are located. Repairing plaster with compo or compo with plaster can lead to the destruction of cast architectural ornaments. Furthermore, chemical paint removers that are safe to use on plaster can deteriorate compo. It is necessary to thoroughly understand the nature of the materials so that informed decisions can be made about their treatments. The study addresses the similarities and differences, the maintenance, deterioration, repair, and replacement of the two materials.

Resumen
Calcium sulphate hemihydrate (CaSO4·0.5H2O), commonly known as plaster of Paris, is used extensively in the construction, ceramics, and medical industries. There are two varieties of plaster referred to as α and β, produced by “wet” or “dry” methods respectively. Plaster hydrates to form crystalline gypsum (CaSO4·2H2O, dihydrate). We present a comparative in situ study of the microstructural changes that occur during the hydration of the two forms of plaster at a water-to-plaster ratio of w/p = 0.8 using NMR relaxometry and electron microscopy. In the α-plaster, pores evolve gradually to form a uniform, interconnected structure. In contrast, the β-plaster hydrates faster, leading to a less homogeneous product with micro-cracks resulting from rapid chemical shrinkage.

Resumen
Lime plasters are mixtures of burnt lime, aggregates and other materials that are employed in masonry architecture. Lime plasters were widely used by the ancient Maya in public monumental buildings and constitute important elements of ancient Maya material culture. This research analyses archaeological samples of lime plasters from three different lowland Maya sites: Palenque, Calakmul and Lamanai. The thesis examines how these building materials changed through time, and includes samples from ca. 400 BC to the 16th century AD. In addition to the analysis of archaeological samples, the research also reviews various sources of information, including ethnographic and ethnohistorical descriptions, for the understanding of ancient Maya lime plaster production. The results demonstrate that plasters from the three sites have different characteristics that are due to different access to raw materials and different building traditions at each of the sites. Some of the changes seem to be related to changing economic and political conditions, which is very clear in the use of clays instead of lime for the manufacture of architectural plasters during the Terminal Classic periods at Calakmul and Palenque. Other observations include the use of local meteoritic deposits in the lime mixtures of Palenque, the use of non-local volcanic materials in the late plasters from Lamanai, and the likely use of volcanic ash at Calakmul for the production of hydraulic plasters. In addition to the technological analyses of ancient plasters, the research also provides suggestions for future research and recommends those analytical methods that are most suitable for the examination of Maya lime plasters.

Resumen
This thesis explores the flowering of decorative plasterwork in late renaissance Scotland, its main focus being what influenced its development, the motivation of its leading patrons, and its role in the culture of Scotland at this time. The thesis begins by assesses why plasterwork has received much less attention in Scotland compared with other building materials, primarily stone, and whether this is as a result of Scotland’s architectural history being misunderstood in its British context. Early seventeenth-century Scotland was experiencing a building boom, its patrons increasingly benefiting from government positions, better education and foreign travel, exposing them to a wide range of influences at a time when houses and estates, (the main signals of status and rank) were being much transformed and domestically improved. This period heralded a burst of decorative plasterwork patronage throughout the country. This thesis analyses the influences which existed in late renaissance interiors in Scotland and whether a native tradition of decorative plasterwork existed in Scotland, and what influence this had on later decorative plasterwork styles. This thesis also gauges the affect that an absent court had on patronage and whether significant cycles of patronage can be interpreted by a study of seventeenth century plasterwork schemes in Scotland, and the role that decoration played in the culture of Scotland at this time. Finally, this research assesses the evolution of plaster throughout the century and why it may have developed differently from English work, and considers the changing role of decorative plasterwork in the late seventeenth century.

Resumen
Liquid, pressurized natural gas in fiberglass tanks is becoming an increasingly common source of energy for the transport sector. The complete product consists of a plastic tank enclosed in fiberglass to achieve the required strength needed. Before the fiberglass coating can be applied, the surface of the tank must first undergo a flame treatment to increase the surface energy of the plastic. In this work, an investigation is made on a previous flame treatment system that could not give the plastic the properties required for a proper attachment of the fiberglass matrix. The measures taken to improve the situation are to implement a new burner system that lives up to the criteria and to investigate the various factors that affect the flame treatment. This can be achieved through a reduced trial planning as a method for evaluating the impact of the contributing factors. The solution is to provide an open ribbon burner with air and fuel through a Venturi mixer. This enables the adjustment of the lambda value to 1.07, which is an essential condition to achieve maximum adhesion to the plastic surface. The stoichiometric ratio of the flame is of great importance to give the plastic a highly polar surface and thereby increases its wettability and adhesiveness. Other significant factors are addressed in the discussion section of the report.
Flytande, trycksatt naturgas i glasfibertankar blir till en allt vanligare energikälla för transportsektorn. De färdiga bränsletankarna består av en plasttank omsluten av glasfiber för att nå upp till den hållfasthet som krävs. Innan glasfibern kan appliceras måste plastens yta genomgå en flambehandling för att öka plastens ytenergi. I detta arbete görs en utredning på ett tidigare flambehandlingssytem som inte kunde ge plasten de egenskaper som krävs för att ge glasfibermatrisen möjligheten att fästa. Åtgärderna är att implementera ett nytt brännarsystem som lever upp till kriterierna och sedan utröna de olika faktorerna som påverkar behandlingen. Detta kan åstadkommas genom en reducerad försöksplanering som metod för att utvärderade bidragande faktorernas påverkan. Lösningen är att förse en öppen bandbrännare med luft och gas genom en Venturimixer. Detta möjliggör en injustering av lambdavärded till 1.07, som är ett viktigt förhållande för att uppnå maximal vidhäftningsförmåga på plastens yta. Lågans stökiometriska förhållande är av stor betydelse för att ge plasten den polär yta som höjer dess vätbarhet och vidhäftningsförmåga. Andra betydande faktorer adresseras i rapportens diskussionsdel.

Resumen
The aim of the presented work was to develop and evaluate the novel thermal insulation plaster intended for repair and renovation application. The thermal parameters of the reference lime plaster were enhanced with the substitution of 50 vol. % of silica sand with expanded perlite. The hardened plasters were characterized by their specific density, bulk density, total open porosity, compressive strength, flexural strength, and dynamic modulus of elasticity. The thermal conductivity and the volumetric heat capacity were investigated as well. As the studied plasters should find use in repair of salt-laden masonry, the specific attention was paid to the assessment of their durability in terms of resistance to salt damage. Plasters were subjected to the accelerated laboratory salt crystallization test that consisted of ten wetting/drying cycles, where the used salt was sodium chloride. For comparison, the same process was performed with distilled water. The salt crystallization resistance was evaluated using the photographical observations and the measurement of the residual compressive strength. The results obtained showed that the use of expanded perlite allows the development of the lightweight repair plaster with sufficient mechanical parameters and improved thermal insulation properties. Moreover, the high porosity of lime-perlite plaster has contributed to its great durability against salt crystallization.

Resumen
Today, it is impossible to imagine life without plastics due to their flexible characteristics. However, the attractive characteristics of plastic in several industries are generating another global problem: waste plastic disposal. According to the “OECD Global Plastic Outlook” published in 2022, global plastic waste production increased by more than 2.25 times between 2000 and 2019 to 353.3 million tons (MMT). However, only 9% of that plastic waste is recycled.
