Abstract

This work is aimed at investigation into oil sludges and their application in the composition of ceramic pastes as energy-efficient and modifying component for production of ceramic bricks. The article discusses the results of experimental study of oil sludges. Innovative engineering approaches to conversion of oil sludge into organ mineral conglomerate state have been developed. It has been established that addition of organ mineral conglomerate mixture with oil sludge converts ceramic paste based on loess loam from high-sensitive matters into low-sensitive ones. Combustion of oil sludge in the composition of organ mineral conglomerate mixture makes it possible to increase temperature in furnace and accelerates baking of ceramic bodies. This is evidenced by reduction in baking time of samples from 9 to 7.5 hours. This process provides decrease in energy consumption at the stage of article baking. Moreover, the weight of final product decreases by 15-20 %, which simplifies labor procedures and increases labor efficiency upon brick laying. Herewith, the load on building foundation decreases, thus reducing material consumption upon construction by nearly 10-12%.
