Extension of Raw Material Base for Ceramic Building Bricks Production

摘要

The purpose of the paper is to determine the possibility of using water purification slime as a raw material in the production of ceramic building brick. The spectrophotometric, power dispersing, atomic and absorption methods of research and biotesting were used. The possibility of using the water purifying slime as a pore-forming component is proved by the production of ceramsite brick. The optimum amount of the component of water purification slime to the main raw materials has been established. The small level of heavy metals leaching from the received construction material has been experimentally proved. The article can be of interest to the experts in the field of creating new construction materials using the production wastes and sewage purifying.
