Abstract


One of the considerations in selecting Glass Fiber Reinforced Polymer (GFRP) as a substitute for conventional reinforcement is its ability against corrosion makes it suitable for structures directly related to land, water, and corrosive areas. In terms of strength, GFRP which has high yield strength is very suitable as a reinforcement to hold the shear force. Similarly as with steel bar, GFRP reinforcement is used as a composite material of reinforced concrete; therefore, it is worth to know the grade of the bond strength. The bond strength is one of the important factors in order to have a good interaction between GFRP and concrete in holding work loads on structures, so that the study is conducted to get the grade of the bond strength of GFRP reinforcement with monolith concrete casted. The experiment is using the pull out test with a cube specimens, sized 250 mm × 250 mm × 250 mm and GFRP bar sized 25 mm diameters. Bond strength of GFRP reinforcement will then be closely compared to the bond strength of BJTS40 deform rebar sized 25 mm diameters. The concrete used in this study has about f'c 100 MPa. The test results indicate the grade of bond strength of GFRP reinforcement with concrete reaches 6.54 MPa and the bond strength of steel bar with concrete  reaches 8.22 MPa. The grade of bond strength of GFRP reinforcement is smaller 79.56% than the bond strength of the steel reinforcement. The failure happened on all test objects is the mode of splitting failure.
