WATER-BASED IMPREGNATING COMPOSITION HAVING ULTRA-CORD HYDROPHOBISATION ACTION FOR PROTECTING SURFACE AND INNER LAYERS OF CONCRETE-BASED STRUCTURES, CEMENT-CONCRETE AND ASPHALT-CONCRETE COATINGS Russian patent published in 2014 - IPC C04B41/61 

FIELD: chemistry.

SUBSTANCE: invention relates to a water-based impregnating composition and can be used to protect the surface layer of concrete, cement-concrete and asphalt-concrete coatings. The water-based impregnating composition having hydrophobisation action for protecting surface and inner layers of concrete-based structures, cement-concrete and asphalt-concrete coatings contains, wt %: coarsely dispersed homopolymeric polyvinyl acetate 10-50, polyvinyl alcohol 5-20, sodium hypochlorite 1-5, water 40-70. The impregnating composition can contain marble calcite in amount of 15-25 wt %.

EFFECT: preventing the effect of harmful components of the impregnating composition on the human body, low water absorption and reagent absorption, high corrosion resistance and frost resistance of concrete or coatings treated with the composition.
