High Mechanical Performance of Reinforced Concrete Wrapped with Carbon-Fiber Polymer and Electrochemical Corrosion Behavior of Carbon Steel in the concrete
One of the solutions proposed by researchers to control the corrosion of reinforced concrete is the use ofwrapping technology. Many researchers have investigated carbon-fiber polymer (CFP) for the aim ofwrapping reinforced concrete. However, the effect of using CFP on the corrosion resistance of concreteshas not been fully studied by researchers. This work focused on the mechanical performance andelectrochemical corrosion behavior of carbon steel reinforced concrete wrapped with CFP. The sampleswere made with one, two, and three CFP layers and tested for corrosion resistance. The orientation ofwrapped CFP has also been studied in this work. The results indicated that the compressive strength ofthe concrete cube samples increased by increasing the CFP layers. Electrochemical impedancespectroscopy tests indicated that the reinforced concrete wrapped with CFP had a higher value of passivefilm resistance compared to plain concrete, indicating more enhancement of corrosion resistance on thesurface of carbon steel rebar.
