Wide Format Ceramic Stones Based on Coal Mining Screenings

This article presents the results of scientific research and laboratory testing of the use of screenings from the Angren coal basin in the production of porous large-format wall stones. In recent years, screenings from the Angren mine have been actively studied as a raw material for porous ceramics. Interest in this coal residue as a raw material for the production of wide format building stones has increased significantly. Energy conservation measures are more cost-effective than those that involve the development of new energy sources. In light of economic reforms and unfavourable environmental conditions in the developed countries of the world, the wise use of fuel, raw materials, and other material resources is increasingly important for the development of ceramic production. In this regard, the problem of obtaining large-format ceramics in the production of wall materials is a particularly urgent and unresolved problem. The most significant factor affecting the level of consistency is observed with an increase in the sintering temperature and an increase in the degree of grinding of the coal screening. The moulding sand used to create wall stones has been subjected to attempts to change its composition. As a result, it was possible to produce a lot of heat-insulating, multi-slit wall stones, which is one of the most promising developments in the field of energy-efficient building.
