The article presents the results of a study of burnt rocks of mine dumps, ash and slag waste and clay raw materials for the purpose of their use in the technology of manufacturing ceramic bricks. Indicators of their quality are given. In terms of properties and composition, this raw material is close to clay. Compositions and technological modes for the manufacture of ceramic bricks using burnt rocks of mine dumps and ash and slag waste have been developed. The results of laboratory research and industrial tests are presented. The possibility of using this technogenic raw material in the technology of manufacturing ceramic bricks has been proven. The use of burnt rocks and ash and slag waste in the compositions for the manufacture of ceramic bricks can improve its quality, including strength and frost resistance. In all respects, prototypes of ceramic bricks meet the requirements of regulatory documents. The involvement of technogenic raw materials in production allows you to save part of natural raw materials, reduce the cost of products while improving their quality, and help reduce the negative impact of waste on the environment in the areas of their location.The involvement of technogenic raw materials in production allows you to save part of natural raw materials, reduce the cost of products while improving their quality, and help reduce the negative impact of waste on the environment in the areas where they are located.
