METHOD OF OBTAINING OF CEMENT MIXING LIQUID Russian patent published in 2014 - IPC C04B40/00 

FIELD: construction.

SUBSTANCE: method comprises electrochemical treatment of mains water in three-chamber electrolysis unit with ion-selective membranes by alternating asymmetric current. Meanwhile the electrolysis unit anode is made from shungite. During the electrochemical treatment of water in the anode and in the anode chamber the ultrasonic oscillations are exited, the frequency of which exceeds the cavitation threshold frequency within a range from 20 kHz up to 100 kHz, and the intensity of the named ultrasonics is in the field of stable cavitation from 1.5 W/cm² up to 2,5 W/cm². Water treatment is stopped at achieving of density of particles of hydrated fullerene 10-3-10-4%.

EFFECT: improvement of frost resistance of concrete mix, increase of cement hydratation level and strength of cement stone in early periods of curing.
