Um dos métodos mais usuais de reparação estrutural é a remoção do concreto deteriorado e sua recomposição por meio da ligação com outro concreto, utilizando produtos denominados pontes de aderência. Entretanto, a falta de normalização e experiência científica acumulada conduz ao emprego desses materiais baseado somente em informações dos fabricantes e em experiências pessoais dos aplicadores, o que mostra a necessidade de um maior número de pesquisas acadêmicas sobre o assunto. O programa experimental desenvolvido avaliou o desempenho de três diferentes sistemas adesivos usualmente utilizados nos reparos estruturais (junta seca, adesivo à base de epóxi e adesivo à base de resina acrilica), por meio do ensaio de compressão-cisalhamento de prismas de concreto reconstituídos com junta diagonal (slant shear test), levando em consideração características como ângulo, umidade e rugosidade da superficie da interface, comparados á prismas monolíticos de concreto e em termos de critério de Mohr-Coulomb. Os resultados mostram que alguns sistemas de reparo podem prejudicar a resistência de aderência, como é o caso dos adesivos à base de resina acrilica, enquanto o epóxi é capaz de promover a aderência até mesmo em situações onde o ângulo da junta é considerado crítico / Abstract: The repair section and concrete reinforcement comes presenting important in the industry of the construction for the increase of the work volume in this area. One of the most usual methods of structural repair is the removal of the deteriorated concrete and its repair by means of the connection with other concrete, using products of adherence. However, the normalization lack and accumulated scientific experience drives to the employment of those materials only based on the makers' information and in personal experiences of the professional, what shows the need of a larger number of academic researches on the subject. The developed experimental program usually evaluated the acting of three diferent adhesive systems used in the structural repairs (it joins drought, sticker to the epoxy and sticker to the base of acrylic resin), by means of the rehearsal of slant shear test of concrete prisms reconstituted with diagonal committee, taking in consideration characteristics as angle, humidity and roughness of the surface of the interface, compared monolithic prisms of concrete and in terms of approach of Mohr-Coulomb. The results show that some repair systems can harm the resistance of adherence, as it is the case of the stickers to the acrylic resin, while the epoxy is capable to promote the adherence even in situations where the angle ofthe committee is considered critical / Mestrado / Edificações / Mestre em Engenharia Civil

Pasportizace stavebně-technického stavu rodinného domu v Hodoníně / Providing measured documentation of existing structural and technical conditions of a house in Hodonín

Kadlčík, Radek January 2016 (has links)
The diploma thesis deals with solving passportization of the existing structural and technical conditions and the proposed modifications family house in Hodonin. The project includes theoretical part describing the defect of brick constructions and other related topics. Next explaining the problems of the building passportization, processing passport current state of the house in Hodonín with the marking of construction defects and failures. Followed by a proposal to repair these defects and failures, increased structural and technical standards. Preparation of a proposal modernization of the building. Compilation itemized budget for individual defects and failures.
