Rebuild : Re-conceiving a sense of place in an industrial wasteland

Pieters, Leoné January 2018 (has links)
The dissertation offers a contribution to contemporary discourse which is greatly concerned with the environmental impact of the built environment. It grapples with issues of man’s identity, a reading of place and the relationship between the habitat and inhabitants, by considering how a post-industrial site, namely the Vereeniging Refractories, can be regenerated. The project investigated the various layers informing place, through the lens of regenerative theory. The purpose is to develop a narrative that is sensitive to the site’s environmental, social and economic context, yet can weave the past, present and potential future together. Various responses to three main design drivers, are explored. Narrative (or heritage), environment and programme were weighed up against each other as architectural informants, to establish the most appropriate hierarchy guiding the architectural product. As programme a vocational college for the built environment is envisioned. In terms of the larger scheme for the site, this will be the first implementation which will facilitate the development of the campus to accommodate various interrelated fields of vocation. Co-dependence, collaboration and integrated learning through doing hands-on activity is explored as a means to build a new relationship between man and environment (as a complete set of ecosystems & narratives) – a relationship rooted in a state of well-being, not one of exploitation and inequality. The approach alternated between qualitative and quantitative research and responses, synthesizing decisions into a balanced response. The programme raised a number of challenges that critically influenced decisions throughout the design process. Accommodation of spaces for academic activities parallel to workshops housing traditional and technologically aided construction largely determined the spatial organization of the project. Iterations based on environmental response and the requirement of the intervention to act as catalyst for future development justified the proposal. The transformation of the skin of a portal frame structure was explored, in order to optimize the building’s response to the natural elements, whilst creating optimal interior spaces. This transformation embodies the narrative and meaning of the place, through integration of different re-claimed brick types and vegetation into the skin of the architecture. The architectural response takes the user on a journey through the transformation from a post-industrial place-less space towards, a place that connects the various layers present, towards the ideal of a dynamic human and natural relationship of well-being. / Mini Dissertation MArch(Prof)--University of Pretoria, 2018. / Carl & Emily Fuchs Foundation / Architecture / MArch(Prof) / Unrestricted

Enhet / Helhet / Unit / Unity

Rovira Torres, Marcelo January 2014 (has links)
Enhet och helhet Av : Marcelo Rovira Torres Var börjar man när ett badhus blir till? Var började badhuset? Kanske var det vid havet, när höstkylan gjorde att vattnet blev för kallt och människor sökte sig till en plats där de kunde simma oberoende av klimatet. Tre badhus som uppfördes under folkhemsbygget under 1900-talets första hälft analyserades i tre svenska städer, Göteborg, Malmö och Luleå. Där framgick det tydligt att fokus låg på motionen och simbanan är byggnadens självklara mittpunkt. Bastun och tvagningen får sett till utformningen en sekundär roll, men funktionen är likväl viktig. Mitt projekt har handlat om att destillera mötet mellan badhusets två huvudsakliga funktioner, motion och tvagning, att skala bort allt överflöd och hitta en arkitektur som kommer så nära byggnadens kärna som möjligt. / Unit and Unity  By: Marcelo Rovira Torres Where does one begin when a bathhouse is in the works? Where did bathhouses originate? Perhaps it was by the sea, when the autumn chill made the water unbearable and people searched for a place where they could swim no matter the climate. Three bathing houses in three Swedish cities, Gothenburg, Malmö and Luleå built during ‘Folkhemsbygget’ in the first half of the 20th century were analysed. There, it was clear that the main focus lay on exercise and the swimming pool for aquatic sports was the buildings undeniable centerpiece. The sauna and ablution seem to have a secondary role, but the function is just as important. This project is about distilling the meeting between the bathhouse’s two main functions, exercise and ablution, to peel away all the excess and find architecture that comes as close to the buildings core as possible.

Användning av den vattenbaserade emulsionspolymeren för utveckling avspecifika egenskaper hos tegel och betong: syntes och karakterisering / Application of the Water-based Emulsion Polymer for Development of SpecificProperties of Brick and Concrete: Synthesis and characterization

Nasr, Shahab January 2022 (has links)
Improvement properties of building materials are essential. In this dissertation thesis, the main concern had been on synthesizing a new resin to improve the properties of concrete and brick. Solvent-based polymers have been used for many years to improve the quality of building materials. In contrast to solvent-based polymers, water-based emulsion polymers are one of the available solutions that have been used to improve the quality of building materials. Several advantages can be enumerated for water-based emulsion polymers such as lower volatile organic compounds (VOC), easier application, lower carbon dioxide emissions in the production, and fossil resource preservation. Water-based emulsion polymers are synthesized from simple homopolymers to copolymers with various monomers and additives. In this research, the synthesis and characterization of water-based acrylic styrene emulsion copolymer had been the main concern. Acrylic monomers could develop the qualities such as thermoplasticity, water solubility, and a longer lifespan of the polymer, while styrene monomers will impart water resistance and stiffness properties. In this research, the first step had been the synthesis of a water-based emulsion copolymer. Furthermore, considering the importance of biodegradability of the synthesized copolymer, the research followed by the replacement of ingredients such as emulsifiers with higher biodegradability characteristics with eco-friendly by-products, i.e. reducing the microplastic hazards. As a result, the copolymer could be decomposed better, and consequently, problems with the release of microplastics will be reduced. The synthesized water-based acrylic styrene emulsion copolymer was characterized by FTIR, DSC, and TGA. The FTIR results confirmed successful emulsion polymerization of acrylic styrene copolymer. DSC results confirmed the formation of an amorphous thermoplastic type of copolymer with a single glass transition temperature. The TGA result also confirms a single decomposition temperature. The film formation was carried out using a film applicator to evaluate the film formation properties. The substitution of the superseded emulsifiers (both anionic and nonionic) did not alter the characteristics of the synthesized copolymer, while some of the qualities such as water absorbance of the dried copolymer are improved (a water absorption test was carried out). To improve the quality of both synthesized emulsion copolymers (with conventional and superseded emulsifiers), the nanocomposite of the emulsion copolymer was prepared (Cloisite 30B at a concentration of 0.2 to 1 %). The synthesized nanocomposite showed better water resistance in the coating application in contrast with emulsion copolymer. The next stage of the research has been concentrated on the application of the synthesized water-based emulsion copolymer to building materials (concrete and brick). The synthesis copolymer has been applied as a coating on the surface of the concrete and bricks. Moreover, the synthesis copolymer was used as one of the ingredients in the mixture of the concrete. The promising results for the coating improved when the synthesis polymer was modified with nanoparticles (Cloisite 30B at a concentration of 1 % weight of the latex). Incorporating the synthesized copolymer in the mixture of concrete caused decreasing in the density of concrete by 4 % ( via air voids formation mechanism). However, water absorption was improved when synthesized copolymer was mixed with the concrete. The synthesized copolymer and the nanocomposite is a suitable coating for the concrete and brick. Furthermore, this copolymer is a suitable water-based coating with improved properties in building materials.

Communal Hall in Hackney Wick

Ebadi, Arshia January 2012 (has links)
Located in eastern London and beside the Olympic legacy there is this knotty hood, called Hackney Wick. A public realm has been proposed in the London Borough of Hackney local development masterplan for this neighbourhood. The project is a communal hall settled in the heart of this town context, has been challenged to tie with the dodgy surroundings. Coming from Olympic park, passing over the separating river and going to Victoria Park, is the main walking and cycling path. Also having the bus route on the same side, makes the northern side more exposed to the people. Facing the northern side of the site is the overground which generates views from the train to the project. As a result, in all the studied schemes, it has been tried to have a big opening looking towards this side. Observing the whole hood, you will find out the context is dominated by typical London brick walls, mostly filled with graffiti arts. This creates a special character for the area, and at the same time brings out some dodgy views. So the idea was to get benefit of the existing wall in the boundary of the site, as a tool to block the ugly views and create an inner paradise, and at the same time, with the aim of the brick nature of that wall, relate to the character of the context. However eventually, it ended up to propose to rebuild the wall with reused bricks, and cover the new added parts in white plaster. So finally, there would be this perception as if there is a new object over the existing, and the old brick wall remains at the bottom exposed to graffiti arts and keeps the same nature as it used to have.

Propuesta de aplicación del método de auto-curado adicionando ladrillo triturado al agregado grueso para disminuir las fisuras superficiales y aumentar la resistencia a la compresión del concreto en zonas cálidas (Lima Norte) / Proposal for the application of the self-curing method by adding crushed brick to the coarse aggregate to reduce surface cracks and increase the compressive strength of concrete in warm areas (North Lima)

Pinchi Morey, Sanddy Rocío, Ramirez Mejia, Hosvick Jeffer 17 February 2020 (has links)
El concreto es uno de los materiales más utilizados en el mundo de la construcción, de las cuales cada material en la mezcla depende de la resistencia que se requiera de acuerdo al análisis estructural. Dentro del proceso de producción de concreto debemos garantizar que el cemento reaccione químicamente y desarrolle la resistencia para la cual fue diseñada, para esto es importante mantenerlo hidratado en ese tiempo mediante el proceso de curado. Una técnica aún no tan conocida es el auto-curado del concreto, por lo cual es una necesidad saber cuál es su influencia en el desarrollo de la resistencia y en la disminución del porcentaje de agrietamiento del concreto en estado plástico. El objetivo de esta tesis es determinar la influencia que tiene el reemplazar un cierto porcentaje de ladrillo triturado como reemplazo del agregado grueso; evaluando la resistencia a la compresión, resistencia a la flexión, y el agrietamiento por contracción plástica del concreto. Se desarrolló con 3 diferentes porcentajes de reemplazo de ladrillo triturado que son: 15%, 21%, 27% del peso del agregado grueso para la resistencia a la compresión (f’c) de 280 kg/cm2. Se concluyó que reemplazo del agregado grueso por ladrillo triturado es efectivo cuando es usado hasta un máximo de 21%. Los resultados obtenidos son óptimos y viables en el tiempo, mostrándonos un aumento en la resistencia a la compresión, resistencia a la flexión y la disminución del porcentaje de fisuras en estado plástico. / Concrete is one of the most used materials in the world of construction, of which each material in the mixture depends on the strength required according to the structural analysis. Within the concrete production process, we must ensure that the cement reacts chemically and develops the resistance for which it was designed, for this it is important to keep it hydrated at that time through the curing process. A technique not yet so well known is the self-curing of concrete, so it is a necessity to know what its influence is in the development of resistance and in the reduction of the percentage of cracking of concrete in the plastic state. The objective of this thesis is to determine the influence of replacing a certain percentage of crushed brick as a replacement for coarse aggregate; evaluating the compressive strength, flexural strength, and cracking by plastic shrinkage of concrete. It was developed with 3 different percentages of crushed brick replacement that are: 15%, 21%, 27% of the weight of the coarse aggregate for the compressive strength (f’c) of 280 kg / cm2. It was concluded that replacement of coarse aggregate with crushed brick is effective when used up to a maximum of 21%. The results obtained are optimal and viable over time, showing an increase in compressive strength, flexural strength and a decrease in the percentage of cracks in the plastic state. / Tesis

Možnosti urychlení doby odležení cihlářských zemin / Possibilities of brick clays ageing ability acceleration

Nečasová, Zdislava January 2012 (has links)
This master thesis is focused on comparing the options available to accelerate thematuring period of brick dough. There were four types of brick clay from differentfactories of the Czech Republic. From each of these four earth were created by three tests. One dough was stored in the laboratory, the second was heated in an oven and the third dough was added sulphite liquor. In these tests was studied mainly maturing and then further the effect the swallowed sulphite liquor on other properties (plasticity, sensitivity to drying, drying change of length and flexural strength). The result of job evaluation should be, how much time and how it will reduce the time of maturing.

Two faces of Nynäshamn / Två ansikten av Nynäshamn

Thysell, Hampus January 2019 (has links)
Ett nytt kommunhus för Nynäshamn stad, belägen i Stockholms län sydspets, vilket innehåller aktivitetsbaserade kontor, ett konstgalleri, kafé och en plenisal. Byggnaden ligger mellan två olika men kompletterande stadsrum vilket byggnaden bemöter med två olika "ansikten", allt medan den fortfarande uppfattas som samma byggnad. Denna idé, vilken kan liknas vid idén om Janusansiktet, har varit min huvudsakliga ingång i det här projektet. Utvändigt både återspeglar ansiktena de stadsrum som äger rum framför och är aktiva i formandet av dess karaktärer. Sammanflätningen mellan de båda sidorna sker istället inuti byggnaden där övergången ömsom är flytande och ömsom skarp med visuella snarare än fysiska kopplingar. / A new municipal building for the city of Nynäshamn, located in the most southern part of Greater Stockholm, including acitivity based offices, an art gallery, café and council chamber. The building lies inbetween two different but complementary public spaces which it adresses with two different "faces" while still being read as one and the same building. This idea, reminiscent of the image of the roman god Janus, has been my main focus through this project. Outwards, the faces both reflect and take an active roll in forming the character of these public spaces while the interweaving takes places inside the building where they sometimes are visually, although not physically connected, and sometimes closer to fade into one another.
