Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an injection repair method of a concrete structure excellent in reinforcing effect of the concrete structure, capable of improving durability of the concrete structure, excellent in waterproofness and excellent in workability. SOLUTION: One liquid moisture solidifying epoxy resin composition 3 containing an epoxy resin, a ketone having a substituent in an αposition and a ketimine compound reacting with a polyamine having two or more amino groups being methylene in the α position in a molecule in 0.5-3 equivalents in active hydrogen equivalent for the epoxy group in the epoxy resin is injected to damage parts 1, 11 at the time when the damage parts 1, 11 of a concrete structure is repaired.
