This work has as its objective to evaluate the effect of the incorporation of a glass polishing waste into heavy clay ceramic, such as bricks and roofing tiles. Formulations were prepared with incorporation of the waste in amounts up to 40 wt.% into a kaolinitic clay. Rectangular specimens were prepared by uniaxial mold-press at 20 MPa and fired at 900, 950 and 1000░C. The waste was characterized by X-ray fluorescence, optical dilatometry and particle size distribution. The physical and mechanical properties evaluated were: linear shrinkage, water absorption and flexural rupture strength. The microstructure of the fired ceramics was evaluated by optical microscopy. The results showed that the waste incorporation significantly improved both the water absorption and the mechanical strength of the ceramic, mainly at 1000oC. Finally, the heavy clay ceramic sector can be an environmental correct solution to this type of waste instead of its disposal in landfill.
