Obtenção e caracterização de um compósito que utiliza rejeitos de brita, cerâmica vermelha e vidro para fabricação de blocos para a construção civil. 2017. 113f. Tese (Doutorado em Engenharia Mecânica) - Centro de Tecnologia, Universidade Federal do Rio Grande do Norte, Natal, 2017.https://repositorio.ufrn.br/jspui/handle/123456789/23954The use of composite materials for civil construction has been the object of academic study in universities and centers of research in Brazil and worldwide. One of the motivating factors is the housing deficit that the countries of the third world are facing. In Brazil, between 2010 and 2014, this deficit reaches more than 6.5 million homes, around 12% of the country's households. This work presents a composite that was obtained from waste generated in the construction industry (gravel and ceramics), glass waste generated by the glazing industry and common elements in construction materials, such as cement, sand and water. These wastes cause great damage to the environment and are disposed of in landfills in large quantities. The work focuses on the use of three residues to obtain the composite and in the manufacture of two types of blocks, a solid one used for floor and one to be used in vertical closings in buildings, being able to be used as structural masonry or of sealing. Twelve formulations were used, two of them serving reference denominated Standard formulations, and later were selected the six of better mechanical results, including a standard with Cement, Average Sand and water. The chosen formulations were characterized, determining the resistance to axial and diametrical compression, water absorption by capillarity and total immersion, density and thermal properties. Blocks were made with two of the best overall composite formulations using specially fabricated forms for this purpose. The most expressive results of the composite were obtained for the mechanical resistance to compression reaching a value higher than 13 MPa, absorption of water with results lower than 7.5 %, Density less than 2.5 g/cm³, Conductivity with values close to 5 W/m.K and diffusivity less than 4 mm²/s. These results allow the composite to be used both in the manufacture of structural and masonry blocks, making it more versatile in the construction industry.Acesso AbertoCompósitoDéficit habitacionalResíduosConstrução civilAlvenariadoctoralThesisCNPQ::ENGENHARIAS::ENGENHARIA MECANICA
