The presented article focuses on the comparative analysis of the physicomechanical and physicochemical properties of the modified gypsum stone and the control compositions. The paper presents the results of a study of the synergistic effect manifested by the influence of additives of fusible finely dispersed clay (siltstone) and dispersed waste powder of the fuel and energy industry in the form of industrial sulfur on the properties of gypsum stone after heat treatment. Analyzing the results showed that along with the joint introduction of additives into the gypsum composition during the mixing process, followed by heat treatment of the products, the strength and water resistance of the final samples increase, for sample GM-3 the strength is 11.7 MPa in 7 days, but for the sample without any additives the strength is 8.28 MPa. Sulfur and siltstone particles are actively involved in the structure formation of gypsum stone, creating conditions for a complex influence due to the modifying effect, which appears as a change in the structure and properties of the composite.
