Estudo da incorporação de resíduo de carvão ativado em argilas de uma olaria de Prudentópolis - PR

Abstract

Red ceramics are clays, which after sintering, and due to the high content of ferrous materials, have a reddish color. In Brazilian industry it is widely used, as in the use of tiles, ceramic blocks and ceramic pieces. Activated carbon, on the other hand, is a material widely used in industry for the treatment and filtration of gases and liquids. This use ends up generating waste, which causes high costs for correct disposal. Therefore, as clays are non-renewable materials, the influence of the addition of activated carbon in the red ceramic mass was studied, studying the physical properties (also known in industries, as ceramic properties) such as: apparent porosity, water absorption, compressive rupture strength, flexural rupture strength (3 points), water percentage for good plasticity and bulk density. It was observed that the percentages with 5%, 10% and 15% increase in its total mass obtained significant results, increasing the strength of the material studied. Based on the experimental data, the environmental and financial impact of the implementation of clay doped with 10% activated carbon residue in the manufacture of ceramic materials in a pottery located in the region of Prudentópolis, Paraná, was verified.
