FIELD: manufacture of building materials.
SUBSTANCE: method consists in preliminarily affecting only tempering water directly in supply tank of concrete-mixing unit by means of high-voltage electric discharges emerging in interelectrode spaces of electrode system followed by adding chemical additives before mixing tempering water with binder and fillers, all operations being accompanied with active agitation by means of air bubbles bubbling through water, e.g. from gas collector with nozzles supplied with air from compressor.
EFFECT: considerably shortened mixing time, improved quality of mix, and reduced consumption of power on activation of water.
