The Northern Region of Rio de Janeiro State is responsible for the production of about 75% of the Brazilian Petroleum (Campos Basin). In the crude oil extraction/separation step, a considerable amount of oil waste is originated, usually named oil sludge waste. The use of this waste as a component of clayey masses is of high interest, as much from an economic and technological as from an environmental perspective. The purpose of this work is to characterize and evaluate some properties of waste containing clayey bodies, aiming its application on structural ceramics. Masses containing 0, 5, 10, 15 and 20 wt% waste were investigated. Results of X-ray analysis, granulometry and Atterberg limits, as well as physical-mechanical properties as a function of waste addition are presented. The results revealed that waste additions modified the physical-chemical-mineralogical characteristics and properties of the masses. The ceramic bodies containing waste are adequate for the structural ceramic field.
