Abstract
In order to prevent corrosion of reinforced concrete, a repair method for reinforced concrete includes a step of injecting a repairing agent containing a layered double hydroxide represented by a layered double hydroxide having a chemical formula represented by M2+1-xM3+x(OH)2(NO3−)x/n·mH2O (M2+ represents a divalent metal, M3+ represents a trivalent metal, and n is a natural number) into concrete from a void on a surface of reinforced concrete, and a step of applying the repairing agent containing the layered double hydroxide to the concrete.
