Abstract
Ceramics for structural blocks are usually composed of a mixture of clays and sand with addition of water before a final temperature sintering. In the molding stage, the mixtures should attend a packing condition between the different particles sizes, to allow required properties of the ceramic after firing. The introduction of another compatible powder material, with a convenient particle size, may improve the ceramic properties such as the strength and water absorption. The number of variables in this system demands a modeling procedure to optimize conditions for the best results. In this work, a Simplex network modeling was used as an experimental planning to determine the optimum combination of clays, sand and water as well as incorporated granite waste, for ceramic blocks fabrication. The pressing load and firing temperature were also used as variables to determine the best response surfaces for final strength and water absorption of the ceramic blocks.
