FIELD: chemistry.
SUBSTANCE: impregnating composition for protecting concrete comprises, by wt %: zinc hexafluorosilicate 5.0-26.0; dihydrogen zinc 5.0-7.0; surfactant 0.1-2.0; water the rest.
EFFECT: reduction in the treated concrete flaking increase its corrosion resistance and moisture protection, protection against the penetration of chemicals and oils, increasing the penetration depth of the impregnating composition in the treated concrete, reducing the viscosity and increasing the shelf life of the impregnating composition, pre-mixing the exception of the impregnating composition before applying.
