HIGHLY STRONG CONCRETE Russian patent published in 2014 - IPC C04B28/04 C04B111/20 

FIELD: chemistry.

SUBSTANCE: invention relates to highly strong concrete, which can be used for manufacturing products for industrial and civil construction, as well as in erecting constructions of special purpose. Highly strong concrete consists of mixture, including Portland cement, sand, broken stone, silica-containing component, represented by sol H₄SiO₄ with density ρ=1.014 g/cm³ and value of pH=4±0.5, additive - polycarboxylate polymer with ρ=1.012 g/cm³ and pH=6±0.5 and water with the following content of components, wt %: Portland cement 15.00-16.93, sand 30.70-32.39, broken stone 44.10-44.12, silica-containing component 0.09-0.10, additive - polycarboxylate polymer 0.18-0.19, water 8.00-8.20.

EFFECT: increased water-tightness, frost resistance and reduction of sagging.
