The paper presents the results of physical and chemical studies of hardening products in the cement-complex additive-water system. The choice of the modifying additive is based on the structural and chemical affinity of the additive fragments with cement, which includes highly dispersed Tarkosil Ts-38 microsilica and MT-600 peat additive. The synergistic effect of the complex additive leads to a significant improvement in the performance characteristics of hydrated cement: strength, frost resistance, water resistance, and others. Physicochemical analysis shows that the introduction of the complex additive increases the density of hydrated cement due to the formation of low-basic hydrated silicates and their kinds, such as afwillite, foshagite, and truscottite.
