this work has as its objective the evaluation of the effect of incorporation of petroleum coke in the physical and mechanical properties of red ceramic. compositions were prepared with 0%, 1%, 2% and 4 wt.% of petroleum coke incorporated into a kaolinitic clayey body. rectangular specimens were formed by extrusion to fire at 850 oc and 1050 oc. the determined physical and mechanical properties were flexural rupture strength and water absorption. the microstructure of the fired ceramics was evaluated by optical microscopy. the results show that the petroleum coke waste can significantly contribute to reduce the energy consumption during the firing stage. however, incorporations must be done in amounts around 1 wt.% to avoid deleterious effect on the water absorption of the ceramic.
