The main objective of this work is to evaluate from an environmental viewpoint the incorporation of solid waste from the siderurgical industry into clayey masses for red ceramics. Ceramic masses containing up to 3 wt% waste were prepared. Ceramic bodies were extruded, dried at 110 °C and fired in an industrial kiln at 950 °C. Leaching and solubility tests were done on the incorporated ceramic bodies. In addition, the emission of gases was also analyzed. The results indicated that the use of up to 3 wt.% siderurgical solid waste in red ceramics does not cause significant environmental impact.
