Low-Quality Brick Clays and Ash and Slag Waste in the Production of Ceramic Bricks

The geography of plants for the production of ceramic bricks for 2023 is analyzed. The experience of a brick factory, where ash and slag waste of the Orenburg region CHP was used as the main raw material, is considered. In factory conditions, the possibility of obtaining ordinary compression-molded ceramic bricks from low-quality raw materials and industrial waste with optimal structure and physico-mechanical properties meeting the requirements of GOST 530–2012 has been confirmed. The results of studies of changes in the chemical, mineralogical composition and technological properties of raw materials are presented. The technology of ceramic brick production, which has passed semi-factory tests, including complex processing of ash and slag waste, is proposed. The physical and technical indicators of the brick prototypes confirm that ASW in a composition with silica gel can be involved in industrial production, which will increase the efficiency of using the natural resources of the Orenburg region.
