In the present work we studied the influence of microwave(ultra high frequency) - processing the modified quartz filler in hardening of gypsum-sand mixtures and strength characteristics. Observed that microwave (ultra high frequency) - processing of surface-modified quartz filler contributes to a marked activation, which is manifested in the change of physico-chemical processes of hardening of products. This fact allows a scientifically-justified to manage these processes and to achieve a very high physical-mechanical characteristics of gypsum-sand compositions.
