HYDRAULIC INSULATION COMPOUND FOR PROTECTION OF CONCRETE AND STONE STRUCTURES "MINSLASH-12" Russian patent published in 2014 - IPC C04B41/65 C04B28/04 C04B111/27 C04B111/72 

FIELD: construction.

SUBSTANCE: invention relates to construction, namely, to hydraulic insulation compounds for protection of concrete and stone structures. A hydraulic insulation compound for protection of concrete and stone structures includes Portland cement of class not less than B 32.5 N, microsilica, sodium silicate in the form of a powdery silicate slab with specific surface of at least 4,500 cm²/g, quartz sand with sand fraction size 0.16-0.63 mm, polycarboxylate, cellulose ether at the following ratio of components, wt %: specified Portland cement, specified microsilica 6.8, specified quartz sand 25.1, specified sodium silicate 4.7, polycarboxylate 0.23, cellulose ether 0.17.

EFFECT: increased water permeability, strength of adhesion with a base, corrosion resistance of structures, reduced subsidence, steam permeability, possibility of efficient usage, both under positive and negative water pressure, for protection of new and repair of old structures.
