METHOD FOR PRODUCTION OF CONCRETE MIXTURE BASED ON ACTIVATED WATER OF TEMPERING Russian patent published in 2014 - IPC C04B40/00 C02F1/48

Abstract RU 2508273 C1

FIELD: construction.

SUBSTANCE: proposed is the method for production of concrete mixture by mixing of cement, mineral aggregates and tempering water activated by magnetic field or simultaneous combined impact of magnetic field and electric current. Tempering water is activated by magnetic field with intensity of 630÷640 kA/m with activation time of 0.9÷0.11 sec. When aggregates humidity is increased, activation time is increased to 0.16÷0.18 sec., or magnetic field intensity is increased to 660 kA/m, or both activation time and magnetic field intensity are increased considering maximum plastification of concrete mixture. When activation is performed by combined impact of magnetic field and electric current, electric current value is set as 0.18-0.2 A with increase to 0.5 or 20-25 A with increase to 250 A depending on the apparatus structure.

EFFECT: improving mixture plasticity, reducing energy consumption due to reduction of temperature of thermo-wet treatment and reduction of time of exothermic exposure.
