Abstract:
Clays are among the most important raw materials due to their numerous industrial functions. In the special case of the red ceramic industry, the clays have wide utility, being the main product for the manufacture of ceramic tiles and blocks, which can be incorporated with industrial waste. This way, the aim of this work was to study the influence of the different types of clays on the quality of sealing ceramic blocks, with incorporated textile mud through the process of solidification/stabilization. It was evaluated the incorporation of textile mud in 5 types of clays which were collected in northern Paraná, Brazil, and a qualitative analysis of ceramic blocks with 15% of textile waste in its composition was performed, in terms of its characteristics, set in the standards of Brazilian Association of Technical Standards. The used residues were provided by 12 textile industries of Maringá, PR, Brazil. Firstly, the characterization of mud and clays was carried out. The ceramic blocks were manufactured in small scale and tested for resistance to compression, leaching, solubilization and water absorption, according to their standards methods. The blocks presented no leaching or solubilization under the studied conditions. Therefore, the manufacture of ceramic blocks has been able to effectively immobilize the metals present in textile waste, showing to be a promising process to minimize environmental impact.
