A method for reinforcing a concrete structure is disclosed in which the steps of (a) applying to a long fiber prepreg an adhesive, (b) attaching on the surface of the concrete structure the long fiber prepreg with the adhesive interposed between the surface of the concrete structure and the long fiber prepreg, and (c) curing the thermosetting resin at an ambient temperature are performed. The long fiber prepreg has as a matrix a thermosetting resin with a curing temperature of 70.degree. C. or above. The adhesive has a curing temperature of from 10.degree. to 40.degree. C., and accelerates the curing of the thermosetting resin impregnated in the long fiber prepreg.

Method for reinforcing concrete structures

A method for manufacturing a concrete structure such as columns and beams with sufficient reinforcement in the shear strength to be durable against earthquakes, etc. A reinforcing member composed of a fiber-reinforced plastic is applied onto the outer periphery of a concrete structural member by winding the fiber strands around the outer periphery of the concrete structural member while impregnating the fiber material with a resin.
