Degradation of Red Ceramic with Incorporated of Petroleum Waste

Abstract:

The red ceramic pieces Campos-RJ degrade easily when they are in the built environment. With the intention to reduce the degradation in these pieces, was introduced petroleum coke in red ceramic. Petroleum coke is a solid fossil fuel, black in color and about granular form. With percentage of 0%, 0.5%, 1% and 1.5% clay added to the coke were obtained is prismatic ceramic samples. After drying at 110 ° C, fired at 800°C and 900°C and carried out at accelerated degradation in the laboratory by degradation equipment, obtaining the technological properties and Weibull distributions before and after degradation in the samples. The 900°C gave the highest Weibull modulus (m = 12.50) compared with the firing pieces at 800°C. The results show that the incorporation of 0.5% of petroleum coke improves the Weibull modulus of the degraded material.
