Electrodischarge activation of sand slime to temper cementitious materials

Abstract

The technological operation of the preliminary simultaneous activation of a filler for artificial building conglomerates and tempering the water by electrodischarge action on sandy slime (a suspension of quartz sand) is discussed. It is shown that there is a physical and chemical activation of quartz sand at the electrodischarge treatment of sandy slime. The activation is determined not only by the deep grinding of the solid phase particles (with the surface energy thus increasing) but also by the obvious damage to the quartz’s crystalline structure (its amorphization).
