The article presents the results of studies related to the development of an effective complex polyfunctional additive (PA), consisting of silicon nanodioxide—Ts38, microsilica (MS), thermally modified peat (MT-600) and marble production waste—microcalcite (MCa), to improve the operational properties cement-based composite materials. A complex of physical and chemical studies was carried out: derivatographic, X-ray phase and electron-microscopic analysis of the control and modified cement stone. It was found that the use of a polyfunctional additive affects the hydration processes of cement clinker minerals, improving both the properties of the cement stone and the properties of concrete. The results of X-ray phase analyzes have shown that the use of a polyfunctional additive leads to a decrease in the intensity of Ca(OH)2 peaks and a change in the phase composition of the cement stone, the formation of a cement stone structure mainly from low-basic calcium hydrosilicates. It is shown that the introduction of a polyfunctional additive in an amount of 5%, with a decrease in cement consumption, makes it possible to increase the compressive strength of the cement stone up to 83% and to form a homogeneous dense structure of the cement stone, which will improve the performance properties of composite materials.
