The present invention relates to a water-soluble polyurethane foam comprising 1 to 99% by weight of an inorganic filler and 1 to 99% by weight of a modified admixture, wherein the modified admixture comprises 25 to 96% by weight of acrylic acid glacial, , 1 to 25% by weight of polybenzimidazole, 1 to 15% by weight of 2-hydroxyethyl acrylate and 1 to 15% by weight of furfuryl alcohol. And a method for protecting a surface of a concrete structure using the same. According to the present invention, excellent strength, abrasion resistance, corrosion resistance, nonflammability, UV resistance, flame retardancy, neutralization resistance, adhesion, freeze-thaw resistance and durability can be realized to increase the durability of concrete structures, have. Also, it is possible to apply the adherend even in the wet state and to exhibit excellent adhesive force, and it is not necessary to dry as in the conventional organic resin, so that the construction period can be shortened and the cost reduction effect can be obtained. |
