Effects of Wrapping Chloride Contaminated Concrete with Fiber Reinforced Plastics

E. W. Berver, J. O. Jirsa, D. W. Fowler, H. G. Wheat, and T. Moon


Damage to concrete due to corrosion of steel reinforcement is a costly maintenance problem that affects infrastructure. Reinforced concrete structures located in an aggressive environment are susceptible. Fiber reinforced plastic composite wraps have recently been used to rehabilitate structures that have experienced damage due to corrosion. Little is known about the long-term performance of FRP composites in corrosion prevention. Corrosion monitoring of laboratory specimens and field research are discussed. A new phase of the project involving the use of corrosion inhibitors prior to wrapping with FRP composites is also described.
