Abstract:
Recent efforts to restore loss of concrete pile capacity caused by corroded reinforcing steel using fiber-reinforced polymers (FRP) have shown promising results. In marine environments, water-activated resins can be used in conjunction with pre-impregnated fibers to eliminate much of the complexity of underwater repair. One such method, which can be directly applied both above and below the water level without a cofferdam, is presented.
