CONCRETE REPAIR WITH EXTERNALLY BONDED FRP REINFORCEMENT

Abstract

A relatively new and little known repair method for concrete structures, including prestressed structures, consists of externally bonding flexible sheets of fiber reinforced plastic (FRP) composites to the concrete surface. Depending on the type of application, the function of the externally bonded reinforcement may be any combination of strengthening, stiffening, crack arrest, or corrosion protection. The author visited Japan in the spring and summer of 1994 and investigated several field applications of this method.
