Abstract

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.
