Study of Influence of Active Mineral Additives on Rheological and Physical-Mechanical Properties of a Gypsum-Cement-Pozzolanic Binder

The diversity of active mineral additives of different origin, mineral composition, dispersion degree and activity, including those which are by-products of industry, makes necessary to study their properties and peculiarities of interaction with gypsum-cement compositions. The studies conducted made it possible to establish the hydraulic activity of mineral additives studied, their influence on the rheological and physical-mechanical properties of a composite binder as well as to determine their optimal content in the mix composition. It is shown that introducing the optimal quantities of studied active mineral additives makes it possible to obtain stable gypsum-cement-pozzolanic systems and improve operational properties of products on their base that results in increasing the bending ultimate strength from 2 up to 48%, compressive strength – from 4 up to 49% and makes it possible to expand the area of their application when manufacturing the wide range of building products.
