Underwater Fiber-Reinforced Polymer Repair of Corroding Piles Incorporating Cathodic Protection

Cathodic protection is a proven method to stop corrosion in chloride-contaminated concrete. On the other hand, the lightweight, high strength, and corrosion resistance of fiber-reinforced polymer (FRP) make it the ideal repair material. This study incorporates cathodic protection within a bonded FRP repair to develop a new system that takes advantage of both technologies. The efficacy of the proposed system is contingent on the integrity of the FRP-concrete bond. Bond is known to be enhanced by the application of sustained pressure. Thus, in segmental construction, a minimum compressive pressure of 276 kPa (40 psi) is applied to join epoxied match-cast units. If uniform pressure can be similarly maintained on the FRP wrap while the resin cures, the FRP-concrete bond may be expected to improve.
