No Brasil, seu emprego concentra-se em forros, revestimentos e paredes divisórias, conhecidas como gesso acartonado. Todavia, o gesso é um material sobre o qual existe pouco conhecimento ao nível da investigação. E este projeto se propõe a estudar mais esse material, através da confecção de compósitos a base de gesso com a incorporação de borracha de pneus, tornando-o assim um material sustentável. A borracha proveniente do processo de recauchutagem de pneus inservíveis tem ampla aplicação em pesquisas com concretos e argamassas; porém pouco se sabe sobre sua aplicação no gesso. Para atingir o objetivo proposto nesse trabalho serão feitos ensaios de microscopia eletrônica de varredura, resistência à ruptura na flexão, resistência à compressão, dureza superficial, absorção de água, densidade superficial de massa, consistência (mini-slump) e comportamento térmico. Dessa maneira, é possível afirmar que a incorporação de borracha pode ser interessante para a produção de placas de gesso, uma vez que pode incorporar um resíduo sem destino totalmente adequado, produzindo placas com características semelhantes das já utilizadas e ainda contribuindo em aspectos como densidade, dureza superficial e isolamento térmico. Sendo assim, dentre as granulometrias utilizadas neste estudo, a borracha grossa pode ser considerada a que teve melhor desempenho, uma vez que apresentou características de ser mais trabalhável, menos absorvente e mais isolante termicamente, além de apresentar resistências à compressão e a flexão adequadas para sua utilização (não estrutural), menores mossas e maior leveza do material. / Gypsum is the oldest constructive synthetic material ever heard, and their widespread use is due to its good thermoacoustic properties and fire resistance. In Brazil, its use is focused on linings, coating and partitions, known as drywall. However, the gypsum is a material on which there is little knowledge in terms of research. And this project aims to study more this material through the production of composite gypsum with tire rubber incorporation, thus making it a sustainable material. The rubber from the retreading process scrap tires has wide application in research on concrete and mortar; but little is known about its application in gypsum. In order to reach the objective proposed in this work, scanning electron microscopy, flexural strength, compressive strength, surface hardness, water absorption, bulk density, consistency (mini-slump) and thermal behavior will be performed. In this way, it is possible to affirm that the incorporation of rubber can be interesting for the production of gypsum boards, since it can incorporate a residue without destination completely, producing plates with characteristics similar to those already used and still contributing in aspects such as density, surface hardness and thermal insulation. Thus, among the granulometries used in this study, the thick rubber can be considered the one that had better performance, since it presented characteristics of being more workable, less absorbent and more thermally insulating, besides presenting resistance to compression and flexion adequate for its use (non-structural), smaller dents and greater lightness of the material. / FAPESP: 2015/17658-4

Det svenska murteglets historia har inte tidigare sammanställts med en bredd över tid och rum. Uppsatsen är skriven i syfte att lägga det historiska pussel som kan berätta hur teglet har använts, vem som har använt det och hur det har förändrats i utseende genom århundradena. Detta har gjorts främst genom litteraturstudier, där källorna sträckt sig över en tidsperiod av 2000 år. Bitar ur varje källa har plockats ut och sedan pusslats ihop för att ge en kronologisk bild över historien. Bilden som trädde fram visade hur katolska munkar tog teglet till Sverige. Det dröjde sedan inte länge förrän kronan och kyrkan också började använda sig av materialet. Först på 1700-talet, tack vare husförhörssystemet som gjorde så att seklets barn lärde sig att läsa, fick teglet sitt genomslag då instruktionsböcker skrevs och spreds över landet. På 1870-talet blev tegelindustrin mekaniserad i stor utsträckning, vilket gjorde branschen känslig för svängningar i landets ekonomi. Utifrån detta dras slutsatsen att läskunnigheten och industrialismen inneburit de största blomstringsperioderna i teglets historia. Ironiskt nog innebar också industrialismen teglets fall, dels genom ekonomisk känslighet, dels genom att betongen tilläts ta över. / The complete history of Swedish bricks has not yet been fully compiled. This paper is written with the intention to assemble the historic puzzle which can tell the story of how bricks have been used, who has used them and how their appearance has changed over the course of time. To do this, extensive literature studies have been made, with sources stretching over a period of 2000 years. Bits of each source have been taken to create a chronological picture of its history. The results showed that catholic monks took the knowledge of brick working to Sweden in the 12th century. Soon, the royal power and the church started using brick as well. Despite this, bricks did not get its biggest breakthrough until the 18th century, when a new church law made children learn how to read. Instruction books got released and were read by a fairly large portion of the Swedish population. In the 1870s, the brickyard industry got mechanized, which made the branch sensitive to changes in the country’s economy. From this, the conclusion is drawn that literacy rate and industrial revolution led to the two biggest blooms in the history of bricks. Ironically, the industrial revolution also lead to the descent of the brick industry, partly because of the economic sensitivity, partly because the concrete was allowed to take over.

The aim of this master’s thesis is comparing prices of building materials wi-thin the building structure in Czech Republic with prices in Poland. The first, theo-retical, part describes differences among the construction classifications and pri-ces. At the end of this theoretical part is written about price calculation of building materials. Specifically about creations of that calculations and comparing between Poland and Czech Republic. The second part is concentrated on created budget and mainly on his bill of materials. The result part is made by comparing of chosen building material pri-ces..

This thesis solves the reconstruction of the former cowshed with neighboring exterior modifications inside the collective farm complex. After the reconstruction the building will perform three functions. The main function will be the building material shop with large warehouses. On the ground floor there will be located the manufacturing of workwear and the administrative part is designed on the second floor above the shop. The renovation will consist of extensive demolition work, especialy the removal of original parts of the roof and supporting walls of the existing building.

L'objet des travaux réalisés dans cette thèse concerne la mise en oeuvre d'un éco-liant à base de co-produits industriels : une cendre volante papetière et un laitier moulu, pour la fabrication de mortiers secs. Cet éco-liant a été élaboré pour remplacer partiellement le ciment comme constituant de matériaux traditionnels d'une part, et recycler en grande quantité l'un des deux déchets industriels, la cendre volante papetière tout en intégrant les notions d'économie circulaire et d'éco-conception d'autre part. La littérature fait état de nombreux travaux sur les différents types de cendres et de laitiers mettant en avant les caractéristiques, la minéralogie, la réactivité de ces cendres volantes papetières et des laitiers moulus. Ces deux coproduits avec environ 20% de SiO2 et 50% de CaO (% pondéraux), ont une composition chimique très proche de celle d'un ciment et développent des propriétés pouzzolaniques qui peuvent suppléer celles du ciment. Leur valorisation comme matériau liant est alors envisageable. Une complète connaissance des propriétés physico-chimiques, structurelles et minéralogiques de la cendre volante papetière et du laitier moulu a conduit à une étude exploratoire de formulations. Des mélanges à partir de 72% de cendres volantes papetières et de 28% de laitier moulu ont été étudiés en se référantà la formulation de base d'un mortier pour en optimiser la teneur en eau et le niveau d'énergie de compactage. Un matériel spécifique pour compacter les éprouvettes prismatiques de dimensions 4x4x16cm3 de mortier a été utilisé. L'effet de l'ajout de trois types d'activateurs i.e. chlorure de calciumCaCl2, métasilicate de sodium Na2O3Si et carbonate de sodium Na2CO3, et d'une faible quantité deciment i.e. 5% et 10% a été analysé mettant en relation la résistance mécanique et la microstructure desmélanges. Deux formulations optimales ont fait l'objet d'analyses relatives à la minéralogie, auxrésistances mécaniques à 2, 7 et 28 jours de cure, à la microstructure avec des images MEB,distributions des pores et à la durabilité. Compte-tenu des résultats satisfaisants obtenus, une approcheà l'échelle semi-industrielle de fabrication de blocs 15x15x15 cm3 à partir des deux formulationsretenues a été menée et discutée. Les premiers résultats montrent un grand intérêt pour la fabricationde pavés et de produits dérivés pour l'aménagement de zones piétonnes ou à circulation réduite. / The aim of this thesis is the development of an eco-binder based on industrial co-products : a wastepapery ash and a ground granulated blast-furnace slag, for the manufacture of dry mortars. On the one hand,this eco-binder was developed to replace partially cement as a constituent of traditional materials, andon the other hand to recycle in large quantities one of these two industrial wastes ; wastepaper fly ashwith considering all the notions of circular economy and eco-design. From literature, there are numerousand relevant research works on the different types of ash and slag, highlighting the characteristics, themineralogy, the reactivity of the wastepaper fly ash and ground granulated blast-furnace slags in details.These two co-products with about 20 wt.% SiO2 and 50 wt.% CaO have a chemical composition veryclose to that of a cement and develop pozzolanic properties that can replace those of cement. Theirvalorization as a binder material is then possible. A complete knowledge of the physicochemical, structuraland mineralogical properties of wastepaper fly ash and ground granulated blast-furnace slag led to anexploratory study of formulations for dry mortars. The mixtures containing 72 wt.% of wastepaper fly ashand 28 wt.% of ground granulated blast-furnace slag were investigated with reference to the formulationof a standard mortar to optimize the water content and compaction energy level. A specific equipment forcompacting prismatic specimens with dimensions 4x4x16 cm3 was used. The effect of adding three types ofactivators i.e. calcium chloride CaCl2, sodium metasilicate Na2O3Si and sodium carbonate Na2CO3, anda small amount of cement i.e. 5 wt.% and 10 wt.% was analyzed. The relation between mechanical strengthand the microstructure of the mixtures has been detailed and discussed. Two optimal formulations wereimplemented and, mineralogy, mechanical strength at 2, 7 and 28 days of curing, microstructure withSEM images, pore distributions and durability have been considered and analyzed. Taking into accountthe satisfactory results obtained, a semi-industrial approach to manufacture 15x15x15 cm3 blocks fromthe two selected formulations was conducted and discussed. The first results show a great interest in themanufacture of blocks of pavement and derived products for the construction of pedestrian or reducedtraffic areas.

Ces travaux de thèse s'inscrivent dans le cadre du projet PNEEB/Typha (Programme National d’Efficacité Energétique des Bâtiments) pour la valorisation d’un roseau invasif, le Typha Australis, comme isolant thermique pour améliorer l’efficacité énergétique des bâtiments au Sénégal. Un agromatériau à base de terre argileuse et de granulats de Typha Australis est élaboré afin d’évaluer l’influence de la morphologie et de la quantité de fibres sur le comportement du matériau. Pour cela, deux modes de production de granulats sont choisis : Une découpe longitudinale et une découpe transversale. Les propriétés physiques sont étudiées (taux de porosité, densité apparente et absolue, microstructure) et la tenue mécanique est déterminée. L'absorption acoustique est également évaluée, de même que les propriétés hygrothermiques et le comportement au feu. Les résultats montrent que la morphologie du granulat de Typha affecte le comportement en flexion, cisaillement et l’absorption acoustique. Son impact sur le comportement de compression est moins prononcé. Une portion plus importante de fibres de Typha réduit la résistance mécanique. En revanche, les performances hygrothermiques sont accrues en raison de la porosité de ces granulats. La fraction transversale de Typha permet d’améliorer la résistance thermique et d’accroitre les phénomènes de transfert de la vapeur d'eau. Cette étude a également permis de montrer que ces matériaux sont d'excellents régulateurs d'humidité. Enfin, les tests au feu révèlent qu’il s’agit de combustibles ininflammables en raison de la présence d'argile. L’influence de la morphologie des granulats n’est pas relevée. / This work is a part of PNEEB/Typha project (National Program for Energy Efficiency of Buildings) for the valorisation of an invasive reed, the Typha Australis, as a thermal insulator to improve the energy efficiency of buildings in Senegal. An agromaterial based on clay soil and Typha Australis is elaborated in order to evaluate the influence of the amount and fibres morphology on the material behaviour. For this, two production mode of granulates are chosen: longitudinal and transversal cut. Physical properties are studied (porosity, apparent, and absolute density, microstructure) and mechanical strength is determined. Sound absorption is also evaluated, as well as hygrothermal properties, and fire behaviour. Results show that granulate morphology affects the mechanical shear and flexure behaviour, as well as the acoustic absorption. Its impact on the compression strength is less pronounced. A greater portion of Typha fibers reduces the mechanical strength. However, hygrothermal performances are increased due to the aggregates porosity. Typha transverse fraction improves thermal resistance and increase water vapor transfer. This study also shows that these materials are excellent moisture regulators. Finally, fire tests reveal that it can be classified as combustible but non-flammable due to the clay presence. The fibres shape does not have a great influence.

Jordens befolkning ökar samtidigt som jordens resurser minskar och klimatförändringarna blir alltmer akuta. Bygg- och fastighetsbranschen står för en betydande mängd av det totala avfallet ivärlden. För att vända denna trend måste återbruk av byggmaterial öka. Idag finns få etableradesystem för att återbruka material som har tjänat sitt syfte i en byggnad. Däremot börjar flera aktörerinse vikten av att ändra flödet av materialen inom respektive organisation och tillämpa metodersom är anpassade för cirkulär ekonomi. För att så mycket material som möjligt ska återbrukas krävsmer omfattande förändringar på samhällsnivå.Det finns åtgärder som varje aktör själv kan ändra för att öka materialåterbruket och därmedminimera mängden avfall. Examensarbetets målsättning är därför att skapa en bild avuppfattningen och arbetet kring återbruk i ett stort svenskt fastighetsbolag och andra aktörer i närasamarbete med Fastighetsbolaget. Existerande utvecklingsmöjligheter har även identifierats för attminska mängden bygg- och rivningsavfall genom att öka återbruket av byggmaterial. Vidare harlösningar föreslagits för hur en byggherreorganisation kan utveckla arbetet med återbruk avbyggmaterial. Syftet med examensarbetet är att öka kunskapen om återbruk för att effektiviseradess implementering och därmed förbättra resursanvändningen ur ett långsiktigt perspektiv.Studien visar att det råder en kunskapsbrist kring innebörden av återbruk och en variation idefinitionen av begreppet, vilka är två viktiga faktorer som försvårar implementeringsprocessen.Kunskapsbristen medför att det är svårt att motivera och öka återbruket i ett redan etableratarbetssätt. För att öka återbruk av byggmaterial i bygg- och fastighetsbranschen måste kunskapenom ämnet öka och spridas, exempelvis genom utbildningar eller god kommunikation inombranschen. De föreslagna metoderna för att öka motivationen är att ledningsgrupper tydligtkommunicerar de mål man vill uppnå och hur dessa mål ska uppnås. Vidare föreslås mer praktiskaalternativ på hur återbruk kan effektiviseras genom att tidigt planera för återbruk vid projekteringenav en byggnad eller lokal, använda standardiserade lösningar, bygga med demonterbara material,införa digitala verktyg för inventering och dokumentering, samt att implementera hyressystem förvaror där ett retursystem till materialtillverkaren möjliggör för ett senare återbruk. / The world population is growing while the planets resources are decreasing, and the climate changeis becoming increasingly acute. The construction and real estate industry accounts for a significantamount of the total waste in the world. To reverse this trend, reuse of building materials mustincrease. There are few established systems today for reusing materials that have served theirpurpose in a building. However, several actors begin to understand the importance of changingthe flow of materials within their organization and applying methods adapted to circular economy.In order for as much material as possible to be reused, more extensive changes are required at thesocietal level.There are actions that each party can change in order to increase material reuse and therebyminimize the amount of waste. The aim of the degree project is therefore to create an image of theperception and work on reuse in a large Swedish real estate company and other actors in closecooperation with the Real Estate Company. Existing development opportunities have also beenidentified for reducing the amount of construction and demolition waste by increasing the reuseof building materials. Furthermore, solutions have been proposed for how a developerorganization can expand their work with reuse of building materials. The purpose of the thesis isto increase the knowledge of reuse in order to streamline its implementation, thus improvingresource use in a long-term perspective.The study shows that there is a lack of knowledge about the meaning of reuse and a variation inthe definition of the concept. These are two important factors that make the implementationprocess difficult. The lack of knowledge means that it is difficult to motivate and increase reuse inan already established working method. In order to increase the reuse of building materials in theconstruction and real estate industry, knowledge of the subject must increase and be spread, eg.through education or good communication within the industry. The proposed strategies forincreasing motivation are that management teams clearly communicate the goals they want toachieve and how these goals will be achieved. Furthermore, the study proposes more practicalalternatives on how reuse can be made more efficient by planning for reuse at an early stage whendesigning a building, using standardized solutions, building with demountable materials,introducing digital tools for inventory and documentation and implementing rental systems forgoods where a return system for the material manufacturer enables a later reuse.

El crecimiento de la población es cada vez más frecuente, lo que implica que las ciudades deben responder a esta demanda mediante la construcción viviendas. Sin embargo, este proceso conlleva una serie de procedimientos que están vinculados a los materiales de construcción, muchos de los cuales generan un impacto ambiental significativo. Por lo tanto, es necesario buscar alternativas que empleen materiales de construcción de base biológica. La presente investigación pretende generar alternativas para la construcción de edificios residenciales en altura en Chiclayo mediante el uso de un material más eficiente para controlar las emisiones de CO2 durante la fase de construcción. Para lograr este objetivo, se diseñó una metodología que se divide en tres fases. La primera se basa un estudio general sobre el impacto de los materiales tradicionales y la madera a partir del análisis del ciclo de vida, mediante los indicadores de la fase de construcción del ACV. La segunda implica el estudio de materiales de base biológica, a partir de sus técnicas y sistemas constructivos. Por último, la tercera fase contempla la generación de estrategias de construcción a partir de los resultados de la primera fase y las técnicas constructivas de la segunda fase. Los resultados obtenidos señalan una eficiencia de la madera para la reducción de emisiones de CO2 sobre materiales como el concreto y acero. Además, dentro de los sistemas constructivos en madera, existe una predominancia por el uso de sistemas combinados y la utilización de madera contralaminada en la construcción de los edificios. / Population growth is becoming more and more frequent, which means that cities must respond to this demand by building housing. However, this process involves a series of procedures that are linked to construction materials, many of which generate a significant environmental impact. Therefore, it is necessary to look for alternatives that use bio-based construction materials. The present research aims to generate alternatives for the construction of high-rise residential buildings in Chiclayo by using a more efficient material to control CO2 emissions during the construction phase. To achieve this objective, a methodology was designed that is divided into three phases. The first is based on a general study of the impact of traditional materials and wood based on life cycle analysis, using the indicators of the construction phase of the LCA. The second involves the study of bio-based materials, based on their construction techniques and systems. Finally, the third phase contemplates the generation of construction strategies based on the results of the first phase and the construction techniques of the second phase. The results obtained show the efficiency of wood in reducing CO2 emissions over materials such as concrete and steel. In addition, within the wood construction systems, there is a predominance of the use of combined systems and the use of cross-laminated timber in the construction of buildings.

Cette recherche porte sur les techniques de production des matériaux de construction en terre cuiteà l’époque romaine dans les provinces de Gaule et de Germanie. Ces techniques ne nous sontaccessibles directement que par l’archéologie, à la fois par les vestiges mobiliers : les matériauxfabriqués eux-mêmes, et par les vestiges immobiliers : les tuileries qui sont régulièrement mises aujour. Seules les structures de production sont examinées, mais il est souvent fait référence auxmatériaux. L’étude est menée selon deux lignes directrices, l’une horizontale : la chaîne opératoire, l’autreverticale : le temps, du présent vers le passé. Les structures de production sont traitées selon l’ordrede la chaîne opératoire : l’extraction, la préparation de la terre, le façonnage, le séchage et lacuisson. À l’intérieur de chacune de ces cinq phases sont étudiées successivement des structuresd’époque contemporaine (ateliers artisanaux), moderne, médiévale et enfin gallo-romaine. Cettedémarche régressive permet de mettre en évidence les continuités et les ruptures dans lestechniques mises en oeuvre et ainsi de mieux caractériser et comprendre la plus ancienne d’entreelles, celle des tuiliers gallo-romains. Le fonctionnement des structures de production les plusrécentes éclaire celui des structures romaines. Des comparaisons ponctuelles ne sont utilisées quepour tenter d’expliquer certaines caractéristiques originales des structures gallo-romaines. Lesrésultats les plus novateurs ont été obtenus dans l’étude des structures employées dans les phasesde façonnage, de séchage et de cuisson. / This research concerns the techniques of tile and brick-making in Roman time in the provinces ofGaul and Germania. We have only access to these techniques through archaeology. First, there arethe movable vestiges: the objects (tiles and bricks), then there are the real estate vestiges: the tilemakingsites which are regularly uncovered. Only the structures of production are examined here,but it is often made reference to materials. The study is led according to two guidelines. One is horizontal: the “chaîne opératoire”, the other is vertical: Time, from present to past. The structures of production are treated according to the orderof the making process: quarrying, preparing clay, shaping, drying, and firing. Inside each of thesefive phases are successively studied structures of contemporary time (craft production), modern,medieval and finally Gallo-Roman. This regressive approach allows us to bring to light thecontinuities and the breaks in the techniques used and thus, to better characterize and understandthe most ancient of them, the Gallo-Roman tile-makers one. The functioning of the most recentstructures of production sheds light on that of the Roman ones. Punctual comparisons are only usedto try and explain some original characteristics of the Gallo-Roman structures. The most innovativeresults were obtained in the study of the structures used in the phases of shaping, drying and firing.

Byggprocesser och produktionen av byggmaterial orsakar stora delar av världens och Sveriges växthusgasutsläpp. För att uppnå en hållbar utveckling är det av stor vikt att minska klimatpåverkan från byggnadskonstruktioner. Genom att göra klimat- och livscykelanalyser av byggnader i tidiga designskeden ökar möjligheten att påverka design, material- och produktval för att minska klimatpåverkan. I denna studie undersöktes hur byggnadsinformationsmodeller (BIM) och BIM-metodik kan användas för ökade möjligheter att effektivt utföra klimat- och livscykelanalyser av ingående byggnadsmaterial iterativt under projekteringsprocessen. Två 3D-modeller importerades till två verktyg för klimat- och livscykelanalyser, Bidcon och One Click LCA. Mängdavtagningen från objekten i modellen till båda LCA-verktygen fungerade automatiskt medan kopplingen mellan objekten och databaser med miljöpåverkansdata för byggobjekt och material innebar mycket handpåläggningsarbete. Processerna förutsätter att modellerna innehåller någon information om de ingående materialen i modellens objekt, vilket därför bör kravställas under projekteringen. För att kopplingen mellan materialbeskrivningar och databaser i LCA-programmen ska ske mer automatiskt bör materialen eller objekten benämnas standardiserat, till exempel med BSAB-koder, ett klassifikationssystem från Svensk Byggtjänst. Benämningarna bör sedan kunna kopplas automatiskt till poster i databaser för effektivare klimat- och livscykelanalyser.  Även intervjuer utfördes, i syfte att undersöka hur metodiken för integrering av BIM och LCA kan tillämpas i byggprojekt. Möjligheten att tillämpa detta i konsultföretag beror på beställarens krav samt i vilka skeden och discipliner konsulterna arbetar. Integreringsprocesser av BIM- och LCA-verktyg borde kombineras med interdisciplinära möten för bättre resultat. Detta tillsammans med ökad efterfrågan på klimat- och livscykelanalyser, exempelvis för att uppnå miljöcertifieringar, kan öka motivationen att använda metodiken. På så sätt kan byggnadsinformationsmodellering användas för effektivare klimat- och livscykelanalyser vilket bidrar till minskad klimatpåverkan från byggnadskonstruktioner. / Construction processes and the production of building material cause a large part of the emissions of greenhouse gases around the world. To achieve a sustainable development it is of great importance to reduce emissions from construction projects. Doing climate analyses and life cycle assessments of building materials during early design phases could enable more sustainable design and material choices. This thesis focuses on Swedish conditions. During this study it was investigated how Building Information Modeling/Management (BIM) can be used to improve possibilities of doing efficient life cycle assessments (LCA) of buildings and included materials, during the whole design phase. Two 3D building models were transferred to two software tools, Bidcon and One Click LCA, for climate analysis and life cycle assessment of the building components. Quantity take-off from the model objects to the tools worked automatically while the connection between the material descriptions and databases inside the tools had to be done manually. The process requires information about the materials in the model to work. To make the connections more automatic, material descriptions need to be more standardized and connect to entries in the databases. Moreover interviews were held to investigate how the methods of integrating BIM with LCA can be used in construction projects. For consulting firms this depends on the demands from the client and which stages of the project the consultants work in. LCA-methods based on BIM should be combined with interdisciplinary meetings for better results. This together with an expanding demand for LCA could increase the motivation to use these methods, which enables reduction of climate impact from buildings.
