(57) [Summary] [Problem] When a carbon fiber sheet is applied to a surface of a concrete structure to reinforce it, the carbon fiber sheet is used as a reinforcing surface even in winter, especially under low-temperature conditions or wet conditions. Provided is a method for reinforcing a concrete structure that can be firmly adhered. In a method of reinforcing a concrete structure by attaching a carbon fiber sheet to a surface, first, a primer resin containing an acrylic resin as a main component is applied on a reinforcing surface, cured, and then carbon fibers are formed. Before and / or after attaching the sheet to the reinforcing surface, a cold-setting resin is applied as an impregnating resin to penetrate into the voids of the carbon fiber sheet, Curing is performed in a state where the carbon fiber sheet and the primer resin are integrated. The acrylic resin includes an epoxy acrylate resin. |
