Study of the expanded clay sand uses in surface and underground mine construction

The possibility of using expanded clay sand in surface and underground mine construction is considered the article. As a result research, material properties were studied, its uses determined. research has experimentally proven that can be used as base for concretes mortars, which are suitable by their properties. In course samples various compositions made; structure shown. Samples tested to determine several physical mechanical Based on experimental data, it was concluded projects, providing strength heat performance structures.
