In this work, the use of residues from the bentonite mining of the State of Bahia, Brazil, in the manufacture of structural ceramic bodies for application in bricks, blocks and tiles is studied. The methodology used in this study consisted of the preparation of common clay specimens with the substitution of clay for the bentonite beneficiation residue in 0%, 5%, 10%, and 20% in weight. After the conformation were done ceramic tests based on ABNT standards for tests such as bending stress, retraction, porosity and water absorption. The clay and the residue were characterized by techniques such as XRD, IR, chemical, thermal and electron microscopy analyzes. The beneficiation residue showed potential use in the manufacture of structural ceramic products.
