METHOD TO PREPARE CONCRETE MIX Russian patent published in 2015 - IPC C04B40/00 C04B28/04 C04B24/00

Abstract RU 2551546 C1

FIELD: construction.

SUBSTANCE: method to prepare concrete mix consists in the fact that previously 50% of the rated amount of cement is mixed with tempering water, containing superplasticiser of the condensation product on the basis of sodium salt of naphthalenesulphonic acid and formaldehyde - RELAMIX T2 and hardening accelerator - sodium sulphate, exposed to mechanical and chemical activation in a rotor-pulsation device for 2 minutes with subsequent mixing of the remaining part of cement and fillers.

EFFECT: increased strength, mobility of concrete mix, frost resistance and water impermeability.
