The aim of the work is to study the use of slag aggregate concrete for the construction of monolithic concrete lining of mine workings. In the coal industry the average of 10-15 m of development workings are constructed to extract 1,000 tons of coal. The monolithic concrete is 97-98% of the total material consumption for the construction of vertical shafts in Kuzbass; lining costs being 50% of the total cost of shaft construction, which are directly dependent on the material consumption and cost. Considering the amount of annually produced coal in Kuzbass mines, it becomes obvious that the cement consumption in the industry amounts to several million tons, the consumption of the aggregates is about ten million cubic meters. It was found that 25-30% of concrete-lined mine workings are relined annually. This is due to the concrete destruction under the influence of unfavorable operating conditions, especially the destructive action of mine water. Therefore, the problem of production of concrete capable of withstanding these phenomena seems quite relevant.

The purpose of the research is to determine the starting material composition, the conditions for its heat treatment and operation, and also the development of the recommendations on the technology of manufacturing and use of slag-foam glass as a structural and thermal insulation material for low-rise construction. Research and development of the composition and technology of ferrosilicate dust - a secondary product of the Novokuznetsk ferroalloy plant and Kemerovo chemical enterprises - slag-foam glass production, were carried out taking intoaccount the need for recycling of waste generated during the production process. The liquid sodium glass production waste is a mixture offerrosilicate dust that is not completely exhausted in the reactors and anaqueous Na2OSiO2 solution. Its density varies from 1.2 g/cm3 to 1.5 g/cm3, and the binding properties are extremely unstable, they depend on the soluble glass and water ratio in the waste. The use of this material as the basis for the production of structural and thermal insulating slag-foamglass with the stable strength index, the average density and the long-term durability is quite relevant.
