What are the primary benefits of strengthening concrete structures with Fiber-Reinforced Polymers (FRP)?

The primary benefits of strengthening concrete structures with Fiber-Reinforced Polymers (FRP) are increased load-carrying capacity, improved durability, and ease of installation. FRP composites are lightweight and have high tensile strength, allowing them to effectively increase the strength and stiffness of concrete members without adding significant weight. FRP can be applied to concrete surfaces to increase flexural capacity, shear capacity, or axial load capacity. FRP also provides a protective barrier that prevents moisture and chlorides from penetrating the concrete, improving its durability and resistance to corrosion. The installation of FRP is relatively quick and easy compared to traditional strengthening methods, such as adding steel reinforcement, minimizing disruption to traffic and reducing construction time. Furthermore, FRP can be used to repair damaged concrete structures, restoring their original strength and extending their service life.
