FIELD: construction.
SUBSTANCE: method of concrete mix preparation consists in preliminary mixing of 50% of rated amount of cement with tempering water containing superplasticiser - Relamix PK, and mechanical and chemical activation in a rotor-pulsation device with the number of rotations of the working organ of 5000 rpm for 2 min, with subsequent mixing of the remaining part of the cement and fillers.
EFFECT: increased strength, frost resistance and water impermeability.
