CONCRETE MIXING WATER ACTIVATION METHOD Russian patent published in 2014 - IPC C04B40/00 

FIELD: construction.

SUBSTANCE: method of activation of concrete mixing water by its modifying with carbon fulleroid nano-particles with its consecutive ultrasonic processing comprises the placement of shungite into a vessel with water, the mass of shungite amount no less than 1% of water mass, and ultrasonic oscillations are excited in water with the frequency in the range from 20 kHz to 100 kHz, from 1.5 W/cm² up to 2.5 W / cm², and 10^-3-10^-5% and water and shungite are subjected to named ultrasonic oscillations within 5-10 minutes until achieving of density of fullerene, emanated from shungite into activated water, then the activated water is passed through the filter and is used as a concrete mixing liquid, and the shungite bottoms are left in the vessel, which is filled with the next portion of water and the procedure of concrete mixing liquid activation is repeated.

EFFECT: improvement of physic-mechanical characteristics of concrete, decrease of water consumption or cement consumption without affecting the concrete strength.
