Main results of the research in the influence of a complex additive on the basis of metallurgical dust and Portland cement on the structure and properties of the gypsum composite are presented. Metallurgic dust, in composition of which complex oxides of iron dominated, was used in the course of the research, the age of the modifier is over 4 years. It is proved that the introduction of complex additives improves physical-mechanical properties of gypsum compositions including the increase in the limits of compression strength by 30%, and reduc- tion in the water absorption. Modifiers, metallurgical dust, and Portland cement influence on the processes of hydration and structure formation of gypsum binders that leads to the for- mation of amorphous products of hydration on the basis of calcium hydro-silicates which bond crystalline hydrates of calcium, fill the pore space of the matrix thus providing the growth of strength characteristics of the material.
