It has been known that acid-resistant concretes on the liquid glass basis have high porosity (up to 18~20 %), low strength and insufficient water resistance. Significant increasing of silicate matrix strength and density was carried out by incorporation of special liquid organic alkali-soluble silicate additives, which block superficial pores and reduce concrete shrinkage deformation. It was demonstrated that introduction of tetrafurfuryloxisilane additive sharply increases strength, durability and shock resistance of silicate polymer concrete in aggressive media. The experiments showed, that the strength and density of silicate polymer concrete increase in case of decreasing liquid glass content. The authors obtained optimal content of silicate polymer concrete, which possesses increased strength, durability, density and crack-resistance. Diffusive permeability of concrete and its chemical resistance has been investigated in various corroding media.

Lime-belite binder is obtained by low-temperature firing of natural marl, marling or sanding limestone and artificial lime-silica mixtures. The binder with calcium oxide also contains significant amounts of dicalcium silicate and some others materials, the composition and quantity of which depend on the chemical composition and firing temperature of the raw materials used. The authors investigated the kinetics of hydration structures and physicochemical properties of lime-based binders on the basis of belitic marl from Akburly and Porlytau. The formation of resistance is associated not only with the formation of the system of different types of structures - coagulation and crystallization, with the transition of the first to the second, but also with the different stages of formation of crystal structures. The possibility of using lime-belitic binders for the preparation of high-strength products of autoclave hardening is proved. The autoclaved binders used in the manufacture of sand-lime products are prepared with the use of mixtures consisting of 60...70 % lime-belite binder and 30...40 % ground quartz sand.
