The paper offers the approach to the integrated utilization of anhydrous calcium sulfate (anhydrite) generated in the manufacture of fluorides and stored as industrial waste. Waste anhydrite can be used to obtain binding materials for dry mortars. Investigated are the anhydrite binders containing disintegrated waste anhydrite and brick dust. It is shown that mechano-chemical activation of binding and filling materials provides favorable conditions for the creation of the surface nanostructures. Together with microfillers, the latter produce a synergetic effect of the pozzolanic activity and crystallization by seeding for anhydrite binders. It is found that microfillers increase the strength properties and water resistance and reduce the setting time of the anhydrite binder. The integrated utilization of anhydrite allows extending the range of gypsum binders and products produced therefrom, addressing environmental problems and reducing the cost of anhydrite finishing materials.
