FIELD: construction.
SUBSTANCE: preparation method of basalt fibre reinforced compositions for dispersion-reinforced foam concrete involves three stage. The first stage involves preparation of a cement and sand mix in a cyclic mixer of a gravitational type, the second stage involves additional wet grinding of the cement and sand mix in a desintegrator, and the third stage involves mixing in a turbulent mixer at mixing speed of 500-600 rpm of the additionally ground wet cement and sand mix during not more than 1.0 minute with a foaming agent till the required value as to density of the prepared mix is achieved, and basalt fibre during not more than 1.0 minute.
EFFECT: improving compressive strength and freeze resistance.
