A UTILIZAÇÃO DE REJEITOS DE QUARTZITOS DO MUNICÍPIO DE GUAPÉ-MG COMO AGREGADO NA FABRICAÇÃO DE TIJOLOS ECOLÓGICOS

Abstract

The city of Guapé, in the south of Minas Gerais, is part of the region called Centro Produtor de Alpinópolis, without regard to the extraction of quartzites, being the second largest producing city, with a production corresponding to 20% of the total extracted in this producer pole. The large scale of quartzite production, especially in the municipality of Guapé, has resulted in a high generation of tailings, causing problems in the environmental sphere, such as silting up streams and altering the landscape, in addition to administrative problems in the mine itself, such as difficulties in maintaining activities and even the impossibility of extraction in areas where there is a tailings deposit, since this is discarded in the mine itself. The objective of this research is to verify a possibility of reusing quartzite tailings in the production of modular soil-cement bricks. The research carried out included a technological study of the collected ones in order to certify the viability of the tailings in the function of soil for the soil-cement brick. The results obtained regarding the technological characterization of the tailings and molded bricks were satisfactory and ensured the feasibility of using quartzite residues in the manufacture of modular soil-cement bricks.
