There was performed analysis of region’s environmental situation, described results of man-induced raw materials’ laboratory studies in the form of bottom ashes mixtures as aggregate and filler for concretes and mortars. Authors developed formulation of composite gypsum binders based on Portland cement, fine ground slag, fly ash and gypsum binder with optimized grain composition of mineral supplements’ particles in composition of formulation. There were examined mechanical and physical properties of CGB. There was determined that usage of fine ground silica containing supplements up to specific surface area 450 m 3 /kg will increase strength properties of concrete based on CGB, ensure effective characteristics of softening factor, water-binder ratio and WPC (water pollution class).
