Technological operation of the preliminary simultaneous activation of filler for artificial building conglomerates and tempering water by electrodischarge influence on sandy sludge (suspension of quartz sand) is discussed. It is shown that there is the physical and chemical activation of quartz sand at electrodis- charge treatment of sandy sludge. Activation determines not only by the deep disintegration of particles (and superficial energy increasing) of solid, but also by obvious quartz crystalline structure's damage, it’s amor- phization.
