Control of corrosion-induced damage in reinforced concrete beams using carbon fiber-reinforced polymer laminates
This study investigates the efficiency of using CFRP (carbon fiber reinforced polymer) laminate to confine the corrosion-induced cracking and to reduce the rate of corrosion activity in reinforced concrete (RC) specimens. From the experiments, the following can be concluded: Corrosion-induced crack width increases with time as corrosion activity progresses. Larger crack widths are obtained at higher levels of corrosion. The maximum permissible flexural crack width specified by North American codes was exceeded at around 3 % mass loss. Comparable rates of corrosion activity were obtained for the shear-span and uniform corrosion beams. Confining the corroded RC beams with CFRP U-wrap reduced the corrosion expansion by up to 70 % for the shear-span corrosion beam and by up to 65 % for the uniform corrosion beam. CFRP U-wrap confinement reduced the corrosion mass loss in the postrepaired beams by 35 and 33 % for the shear-span and uniform corrosion beams, respectively, compared to the unwrapped corroded beams.
