Reinforced concrete structures are vulnerable to the corrosion of reinforcing steel, which is typically caused by the neutralization of concrete and the presence of surrounding chlorides in various environmental conditions. This corrosion leads to cracking in the concrete, thereby reducing durability of the structure and shortening its lifespan. To address this issue, there has been an increasing interest in research on Fiber Reinforced Polymers(FRP), particularly Carbon Fiber Reinforced Polymer(CFRP). CFRP, composed of carbon fibers, is noted for its lightweight properties, outstanding tensile strength, and high elastic modulus. It also offers excellent corrosion resistance and durability against weathering. Despite the potential benefits, the data on CFRP's performance and integration into reinforced concrete structures remain limited. This study contributes fundamental data regarding the application of CFRP, highlighting its advantages and exploring its practical implications. A significant finding from this research is that concrete specimens cured underwater exhibited superior bond strength compared to those cured under dry conditions. |
