Resumo: | In this work the properties of the reinforced structural concrete with polypropylene treated bamboo fibers were studied and they were compared with the properties of the structural concrete without addition of fibers and with the addition of steel fibers. Much has been studied regarding reinforced concrete with different fibers. Among the natural fibers, bamboo fibers are among those that present a good mechanical performance and can be compared to steel. One of the factors that prevent its indication for its use in the construction industry is due to the fiber's water absorption capacity, which results in the loss of the mechanical properties of the fiber and, consequently, of the concrete. In order to decrease the water absorption by the fibers, they were treated with polypropylene (PP) in solution, to waterproof the fiber and to guarantee the resistance to the requested stresses of the structural concrete. Three types of structural concrete were obtained: structural concrete without fiber addition, structural concrete with 8 % by volume addition of bamboo fibers, and structural concrete with 8 % by volume addition of steel fibers. The different types of concrete were characterized by mechanical, morphological and microstructural tests. The partial results showed that the different types of concrete can be classified as excellent and that the concrete containing steel fibers is more resistant although the reinforcement matrix interaction was higher for the concrete obtained with bamboo fibers coated with PP. |

Muito se tem estudado a respeito do concreto reforçado com diferentes fibras. Entre as fibras naturais, as fibras de bambu estão entre as que apresentam um bom desempenho mecânico podendo ser comparado ao do aço. Um dos fatores que impede sua indicação para o emprego na construção civil deve-se a capacidade de absorção de água pela fibra, que resulta na perda das propriedades mecânicas da mesma e, por consequência, do concreto. Visando diminuir a absorção de água pelas fibras, estas foram tratadas com polipropileno (PP) em solução, para impermeabiliza-las e garantir a resistência aos esforços solicitados do concreto estrutural. Foram obtidos três (03) tipos de concreto estrutural: concreto estrutural sem adição de fibras, concreto estrutural com adição de 8% em volume de fibras de bambu e, concreto estrutural com adição de 8% em volume de fibras de aço. Os diferentes tipos de concreto foram caracterizados por meio de ensaios mecânicos, morfológicos e microestruturais. Os resultados mostraram que os diferentes tipos de concretos podem ser classificados como excelentes e que o concreto contendo fibras de aço é mais resistente embora a interação matriz reforço tenha sido maior para o concreto obtido com fibras de bambu revestidas com PP.application/pdfporUniversidade Presbiteriana MackenzieEngenharia de MateriaisUPMBrasilEscola de Engenharia Mackenzie (EE)http://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessconcreto de alto desempenhofibras de bambufibras de bambu revestidas com polipropilenofibras de açopropriedades mecânicas do concretoCNPQ::ENGENHARIASCNPQ::ENGENHARIAS::ENGENHARIA CIVIL::CONSTRUCAO CIVIL::MATERIAIS E COMPONENTES DE CONSTRUCAOTratamento de fibras de bambu com polipropileno para utilização em concreto estruturalinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisMiranda, Leila Figueiredo dehttp://lattes.cnpq.br/0218222413589119Munhoz Junior, Antônio Hortênciohttp://lattes.cnpq.br/8233884614933594Valenzuela Diaz, Francisco Rolandohttp://lattes.cnpq.br/3539158603053300http://lattes.cnpq.br/6295014221946540Carraro, Cristine Grassellihttp://tede.mackenzie.br/jspui/retrieve/17490/Cristine%20Grasselli%20Carraro.pdf.jpghttp://tede.mackenzie.br/jspui/bitstream/tede/3719/5/Cristine%20Grasselli%20Carraro.pdfhigh performance concretefibers made of bamboobamboo fibers coated with polypropylenefibers made of steelmechanical properties of concretereponame:Biblioteca Digital de Teses e Dissertações do Mackenzieinstname:Universidade Presbiteriana Mackenzie (MACKENZIE)instacron:MACKENZIE10899/242492020-05-28 15:07:40.196Biblioteca Digital de Teses e Dissertaçõeshttp://tede.mackenzie.br/jspui/PRI |
