The diversity of active mineral admixtures of different origin, mineral composition, dispersion and activity, including by-products in many industrial processes necessitates investigating their properties and characteristics of interaction with gypsum cement compositions. Completed research allowed to define the hydraulic activity of the investigated mineral admixtures and their effect on the rheological and mechanical properties of the composite binder, as well as to determine their optimal content in the mixture. It was shown that the use of the tested active mineral admixtures in optimal amounts allows to obtain stable gypsum cement-pozzolanic system and improve the performance properties of products based on them, resulting in increase of the tensile strength in bending from 2 to 48%, at a compression - from 4 to 49% and can significantly extend the range of use them in the manufacture of a broad spectrum of building products.
