TECHNIQUE PROTECTING ELECTRODES IN PROCESS OF ELECTRIC HEATING OF CONCRETE MIXTURE Russian patent published in 2002 - IPC

FIELD: civil engineering. SUBSTANCE: technique protecting electrodes in process of heating of concrete mixture is carried out by installation of phase electrodes in body made up of electric insulation and metal plates utilizing current-conducting fixtures. Phase electrode are buried tightly over largest part of perimeter in grooves of electric insulation plates to depth not smaller than thickness of phase electrode which is assumed to be sufficient to take mechanical loads. In this case free butts of phase electrodes are positioned above level of concrete mixture. EFFECT: enhanced functional reliability and prolonged service life of phase electrodes. 2 dwg
