ABSTRACT:
After sanding the upper surface 6 of a concrete slab 2, thermosetting resin 13 is poured onto the upper surface, and a unidirectional reinforcing fiber sheet is laid on the resin 13. The reinforcing fiber sheet is supported on the upper surface of the slab at the ends of the sheet by anchor pins 14 and maintained in a stretched state, to thereby impregnate the resin into the sheet and adhere the sheet to the upper surface of the slab. The resin-impregnated fiber sheet is then cured to reinforce the slab. The resin used has a viscosity of 5,000 cP or less at 20.degree. C., a thixotropic index of 3 or less at 20.degree. C., and a glass transition point of 60.degree. C. or greater after hardening.
