METHOD FOR ELECTRICALLY HEATING CONCRETE MIXTURE Russian patent published in 2003 - IPC

FIELD: building industry, namely electric heating of concrete mixture directly in building zone and in plant condition. SUBSTANCE: method comprises steps of placing electrodes for electrically heating concrete mixture by pairs in cylindrical reservoir; placing electrodes of each pair in parallel one relative to another and symmetrically relative to central axis of said reservoir; at first applying electric current to one pair of electrodes; then cutting off said pair of electrodes and simultaneously applying current to next pair of electrodes. EFFECT: uniform heating of concrete mixture in the whole volume of reservoir. 1 dwg
