Avaliação da incorporação de pedra Cariri em massas de tijolos de cerâmica vermelha

Abstract

The red ceramic industries have great importance in the region as well as the mining and laminated limestone processing represent an important economic sector of the State of Ceará, but produce a lot of waste that pollute and damage the environment. Thus, this study aims to characterize the residue incorporation of Cariri Stone evaluating its applicability as an alternative ceramic raw material for the production of ceramic tiles. compositions were formulated containing the residue and made bodies of the test piece by pressing. The bodies of the test piece were burned and then were determined color after firing, loss on ignition, linear shrinkage, water absorption, apparent porosity and modulus of rupture in bending. We obtained a with red, with a lighter shade on who had the pedra-cariri in weight. It was also seen porosity, together with an acceptable level of water absorption for ceramic bricks and the breakdown stress increased by 5% and fell by 10%. After all the tests performed, it has been proved that the waste is able to be used for the incorporation of up to 5% in formulations for the production of ceramic tiles.
