UTILIZAÇÃO DE REJEITOS DE QUARTZITO DO MUNICÍPIO DE GUAPÉ-MG COMO AGREGADO NA PRODUÇÃO DE TELHAS DE CONCRETO

Abstract

The municipality of Guapé-MG is part of one of the quartzite producing centers in the south and southwest of the state of Minas Gerais. Quartzite is extracted in the form of plates and widely used in civil construction as a coating, however, in its extraction and cutting process there is a large production of waste that ends up being discarded in inappropriate places. This type of waste inserted in the production of concrete can generate numerous benefits, from the environment to the final product under research, since the transport of waste from the quarry to a disposal site becomes impracticable, thus, using it as aggregate, a new direction can be drawn for quartzite waste, generate new jobs and manufacture a sustainable and low-cost product. The objective of this work is to verify the possibility of using quartzite tailings as an aggregate in the production of concrete tiles from a study of their physical and mechanical properties. The work consists of a bibliographic review emphasizing concrete tiles and quartzite tailings, a description of the place where this tailing was taken and sampling, the characterization of the materials, production of the tiles and finally, the tests normative executed with concrete tiles which obtained both satisfactory and unsatisfactory results. All the tiles met the normative load requirement when flexing rupture, but their water absorption exceeded the limit established by the norm.
