VIABILIZAÇÃO DE REJEITOS DE VIDRO PARA PRODUÇÃO DE TIJOLOS CERÂMICOS/VIABILITY OF WASTES GLASS FOR THE PRODUCTION OF CERAMIC BRICKS

Currently are consumed large quantities of materials for the construction of popular housing. Based on this situation, the work aims to produce ceramic blocks with the reject of crushed glass. The glass powder was evaluated by laser granulometry, X-Ray Fluorescence and X-Ray Diffraction. The cylindrical specimens composed by cement, sand, gypsum, lime and ground waste glass were made. The glass waste underwent by sieving process, obtaining a glass powder thinner, which provided a better mixing between the constituent elements of the composite. A practical use of the composite would be the production of lightest constructive block with greater thermal resistance and cheaper than those produced by conventional materials. From the characterization of these ceramic blocks obtained with the glass waste was achieved, to identify the thermal comfort conditions and mechanical resistance. It is important to consider that, the use of powder glass in the manufacture of blocks implies the reduction of glass waste, which probably would have been discarded in the environment.
