The objective of this work was to evaluate the effect of incorporation of rubber powder waste from the tire retreading industry in technological propertires of heavy clay ceramics. The raw materials were initially characterized in terms of its mineralogical and chemical composition by XRD and XRF, respectively. The firing behavior of the waste was evaluated by DSC/TGA. Compositions were prepared with amounts of waste 0; 0.5; 1; 1.5 to 2 wt.% incorporated into the clayey body. Specimens were prepared by 18 MPa uniaxial pressure and then fired at 850 and 950oC. The results indicated that the investigated waste can contribute to saving energy during the firing stage of the ceramic due to the high amount of carbon. With respect to the technological properties, it was observed that the waste increased the porosity of the ceramics with incorporations in higher amounts, but the mechanical strength was not impaired.
