Abstract
The gradual reduction of traditional raw materials for the production of mineral porous thermal insulation materials forces enterprises to look for alternative types of raw materials, including those from waste. The developments of foreign and domestic scientists have shown the possibilities of using unconventional raw materials of natural and man-made basis, which is considered as a complex use of mineral raw materials. The use of large-tonnage by-products of industry in the production of mineral thermal insulation materials expands the raw material base which contributes to the disposal of industrial waste and improves the environmental situation in the regions. When using associated products, the costs of field development are excluded, which reduces the cost of production. In this work, on the basis of overburden rocks of coal mining – mudstones, soda ash and crushed limestone, a granular thermal insulation material was obtained, the characteristics of which are much better than traditional expanded clay gravel obtained from clay rocks. The resulting porous material in the form of granules will be used as an effective thermal insulation filling and as a filler in the manufacture of light concrete.
