COMPOSITION FOR THE CONCRETE STRUCTURE REINFORCEMENT, THE REINFORCING PASTE, AND THE REINFORCING METHOD USING THE SAME

摘要

The present invention relates to a composition for reinforcing a concrete structure comprising: a principal member including 40 to 50 parts by weight of a cycloaliphatic compound epoxy resin, 15 to 30 parts by weight of a bisphenol A type epoxy resin, and 20 to 40 parts by weight of a phenyl glycidyl ether epoxy resin; a hardener including 5 to 10 parts by weight of modified aliphatic polyamine, 5 to 20 parts by weight of an anhydride hardener, 10 to 15 parts by weight of a polymercaptane hardener, and 10 to 15 parts by weight of a phenalkamine hardener; and an elastic filler including 20 to 35 parts by weight of acrylic emulsion, 5 to 10 parts by weight of titanium oxide, and 5 to 10 parts by weight of calcium carbonate, and to a reinforcing paste and a method for reinforcing the concrete structure using the same. The present invention has excellent adhesion property to the concrete structure, and also durability.
