Abstract (en)

The present invention relates to repair and reinforcement of existing concrete structures such as bridge footings and buildings. The repairing and reinforcing method of the present invention is characterized by applying a reinforcement fiber sheet material having a resin content of 15% by weight or less to the surface of the existing concrete structure while being impregnated with a resin having a viscosity within a range of 2.5-300 poise and a curing time within a range of 1-24 hours, and curing the resin. According to this method, existing concrete structures can be repaired and reinforced easily in a short time without being influenced by temperature conditions on execution, while providing concrete structures with high strength.
