Applications of GFRP Rebar in Bridges, Marine Structures & Tunnels
In modern infrastructure projects, steel is no longer the first choice for reinforcement. Engineers and planners are questioning the long-standing assumptions, especially in environments where corrosion, moisture, and chemicals shorten the lifespan of concrete structures. This shift in thinking has opened the door to alternatives that solve problems steel has struggled with for decades. One such alternative is glass fiber reinforced polymer rebar . While it may not look very different from conventional reinforcement at first glance, its behaviour inside concrete is entirely different. Instead of rusting, expanding, and cracking concrete from within, it remains stable in harsh conditions where steel usually fails. What is glass fiber reinforced polymer rebar? Glass fiber reinforced polymer rebar, also known as GFRP rebar, is a non-metallic reinforcement made by embedding high-strength glass fibers into a polymer resin matrix. The result is a lightweight yet strong reinforcing bar design...
