Resumo: | This work aims to evaluate the concrete with addition of hollow glass microspheres . The specific objectives of this work is to evaluate the influence of the addition of hollow glass microspheres with different combinations of dosage in concrete concerning resistance and workability. It was proved that in other studies glass microspheres may influence the workability of the concrete , because due to its geometry, the balls can roll on each other and on the other solid components of the concrete. In view of the foregoing, it becomes important to study the effect of varying the dosage of these glass microspheres in the concrete properties, such as fluidity, strength and compactn ess. Tests are carried out Workability Slump in each dosage of concrete , and in every age of curing of concrete , the bodies of the test piece was be submitted to ultrasound and axial strength test . we used the Weibull to compare the results. With the results obtained in the tests, the comparative analysis of the variation of each factor chosen were performed. The analysis of the results shows that for some formulations, the addition of hollow glass microspheres imparts high mechanical strength to compressive strength above 30MPa at all periods analyzed. Importantly, the workability of the concrete had to be substantially reduced, showing no improvement in workability due to the addition of hollow glass microsphere |

O objetivo específico deste trabalho é avaliar a influencia da adição de microesferas ocas de vidro com diferentes combinações de dosagem no concreto, em relação à resistência e à trabalhabilidade. Foi provado em outros trabalhos que as microesferas de vidro podem influenciar na trabalhabilidade do concreto, pois, devido a sua geometria, as esferas podem rolar umas sobre as outras e sobre os demais componentes sólidos do concreto. Em virtude do exposto, torna-se importante estudar a influência da variação da dosagem dessas microesferas de vidro nas propriedades do concreto, como fluidez , resistência e compacidade. Foram realizados ensaios de trabalhabilidade ou Slump em cada dosagem de concreto, e em cada idade de cura do concreto, os corpos-de-prova foram submetidos ao ultrassom e ao ensaio de resistência axial, utilizou-se o método de Weibull para comparar os resultados de resistência a compressão. Com os resultados obtidos nos ensaios, foram realizadas as análises comparativas da influência da variação de cada fator escolhido. A análise dos resultados obtidos mostra que para algumas formulações, a adição das microesferas ocas de vidro confere alta resistência mecânica de compressão do concreto, acima de 30MPa, em todos os períodos de cura analisados. Importante destacar qu e a trabalhabilidade do concreto apresentou-se substancialmente reduzida, não apresentando qualquer melhora de trabalhabilidade devido à adição da microesfera oca de vidro.Fundo Mackenzie de Pesquisaapplication/pdfporUniversidade Presbiteriana MackenzieEngenharia de MateriaisUPMBREngenharia de Materiaisconcretocimentomicroesferas ocas de vidrocementhollow glass microspheresCNPQ::ENGENHARIAS::ENGENHARIA DE MATERIAIS E METALURGICAConcreto com adição de microesferas ocas de vidroinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisMunhoz Junior, Antonio Hortênciohttp://lattes.cnpq.br/8233884614933594Zandonadi, Alexandre Romildohttp://lattes.cnpq.br/0237917889413208Diaz, Francisco Rolando Valenzuelahttp://lattes.cnpq.br/3539158603053300http://lattes.cnpq.br/5914245622646949Peres, Cindy Yuri Uekihttp://tede.mackenzie.br/jspui/retrieve/3611/Cindy%20Yuri%20Ueki%20Peres.pdf.jpghttp://tede.mackenzie.br/jspui/bitstream/tede/1343/1/Cindy%20Yuri%20Ueki%20Peres.pdfinfo:eu-repo/semantics/openAccessreponame:Biblioteca Digital de Teses e Dissertações do Mackenzieinstname:Universidade Presbiteriana Mackenzie (MACKENZIE)instacron:MACKENZIE10899/241752020-05-28 15:07:28.082Biblioteca Digital de Teses e Dissertaçõeshttp://tede.mackenzie.br/jspui/PRI |
