Silicate polymer concrete

It has been shown that acid-resistant silicate polymer concretes based on liquid glass have high porosity (up to 18% to 20%), low strength and pot life, large shrinkage deformation, and insufficient water resistance. Therefore, they cannot be used as materials for load-bearing structural elements.

Silicate polymer concrete (SPC) is used in the repair of foundations, for the manufacture of storage tanks for hot and cold acids, equipment lining, reservoirs, and building structures, and as the structural material in vessel heads, vaults, and diaphragms. SPC is of particular interest in precast structures in production of pickling baths for metallurgical plants.

One can see that the compressive strength of silicate polymer concretes modified by additive WSS increases by 30%, and water permeability is reduced by more than 15 times in comparison with concrete without the additive.
