Bond Strength Properties of GFRP and CFRP according to Concrete Strength

Reinforced concrete is the most commonly used material in construction industry. However, one disadvantage of reinforced that environmental factors cause materials to penetrate and steel bar corrosion. Rebar corrosion increases its volume significantly by approximately 3–6 times, which lowers concrete–rebar adhesion. This severely affects serviceability durability structures. The economic social impacts such deterioration are extremely large. To reduce corrosion, glass fiber-reinforced plastics (GFRP) carbon (CFRP) can be applied concrete. rebar–concrete bond strength an important factor considered while applying GFRP CFRP. Thus, we experimentally investigated adhesion CFRP relation water–cement ratio according ASTM C 234 correlate data for development as substitutes deformed reinforcing bars. results showed a lower yielded higher compressive strength; was 23% than coating rebar surface required application structures ought future.
