FIELD: manufacture of building materials; production of gypsum binders.
SUBSTANCE: proposed method includes crushing gypsum binder, mixing it with modifying additive, dehydration of mixture thus obtained for making the binder; used as modifying additive is carbonate-containing sludge of water softening process of thermoelectric plants which is preliminarily dried to constant mass; used as gypsum raw material is gypsum stone; modifying additive may be used at the following ratio of components, mass-%: gypsum raw material, 85.0-95.0; modifying additive, 5.0-15.0.
EFFECT: reduction of binder setting time at retained strength; facilitated procedure of production of gypsum binder.
