Benefits of using GFRP Rebar in Bends in Diaphragm Wall Construction:

• Corrosion Resistance: GFRP rebar is inherently resistant to corrosion and electrochemical degradation, ensuring long-term durability and structural integrity in diaphragm walls exposed to harsh environments such as marine or brackish water.
• Extended Service Life: By eliminating the risk of rust and corrosion, GFRP rebar significantly extends the lifespan of diaphragm walls, reducing maintenance costs and the need for frequent repairs or replacements.
• Lightweight and High Strength: GFRP rebar offers a high strength-to-weight ratio, making it lighter than steel reinforcement yet maintaining excellent tensile strength. This facilitates easier handling, lowers transportation costs, and improves the efficiency of diaphragm wall installation.
• Non-Conductive Properties: The non-conductive nature of GFRP bars eliminates the risk of stray current-induced corrosion, enhancing the durability and reliability of reinforced concrete diaphragm walls near electrical installations or cathodic protection systems.
• Improved Structural Integrity: GFRP rebar’s corrosion resistance minimizes the risk of concrete cracking and spalling caused by reinforcement corrosion, ensuring the long-term integrity and load-bearing capacity of diaphragm walls.
• Reduced Embedment Length: GFRP rebar’s high tensile strength and bond characteristics allow for reduced embedment lengths compared to traditional steel reinforcement, potentially reducing overall construction time and costs.
• Resistance to Fatigue: GFRP rebar exhibits excellent resistance to fatigue, making it suitable for diaphragm walls subjected to cyclic loading conditions, such as those in marine structures or foundations.
