Concrete repair with externally bonded FRP reinforcement

A fairly new and little known repair technique for concrete structures, including prestressed structures, comprised of externally bonding flexible sheets of fiber reinforced plastic composites to the concrete surface. The function of the externally bonded reinforcement may be any combination of strengthening, stiffening, crack arrest, or corrosion protection, depending on the type of application. Several field applications of this technique as used in Japan were examined and cited in this article.
