Abstract
This paper reviews the issue of selecting the compositions of ceramic masses for the production of ceramic blocks made out of technogenic raw materials of a coal series using the methods of mathematical planning. The possibility of replacing classic clay raw materials with non-traditional coal technogenic raw materials (screenings of heaps), which are formed during the processing of heaps with the aim of extracting coal, is considered. The reasons for the growing interest in this technogenic raw material were the reduction of the base of high-quality clay raw materials, the large number of accumulated heaps, as well as the need to reduce the cost of production of ceramic blocks.
Highlights
In recent years, active development of heaps of East Donbass with the goal of coal extraction has been carried out, which has significantly increased the interest of the construction materials industry in by-products of their development
The concept of using energy-saving and environmentally friendly technologies in the production of ceramic building materials is becoming increasingly important in the world
One of the promising areas of development can be considered the production of highly efficient ceramic stones from 2.1 NF and above
Summary
Active development of heaps of East Donbass with the goal of coal extraction has been carried out, which has significantly increased the interest of the construction materials industry in by-products of their development. For the production of ceramic samples, technogenic raw coal materials (screenings) are used with the addition of clay in the amount of 10-30%.
