The research addresses this second stage, binary mixtures of clays Ceramic Santa Rita and the Cooperative of Artisans from Foz do Iguaçu, PR, in different weight percentages, for making specimens by uniaxial pressing, sintered at temperatures of 950 and 1050 ºC, and analyzed by technological tests of red ceramic. In compositions among the clays that were better at processing, proportions of 4, 8, 12 and 16% of the waste sludge were added in order to add mass. It was identified in the results of the production of building blocks 6-hole extrusion process by which 8% is the maximum of sludge to be added to the ceramic body, which was not identified cracks and deformations with linear shrinkage in the order of 8.6% water absorption of 24.6% and compressive strength of 42.6 kgf/cm² in accordance with the standards for the production of red ceramic coating (bricks).
