In this study, an experimental evaluation was made on the change of the pull - out performance of BFRP concrete interface after repairing cracks on the lower surface of reinforced concrete by using basalt fiber which is environment friendly and heat - resistant compared to glass fiber. The test standard was ASTM D7522 / D7522M, and the influence factor was considered as the crack thickness. Test results showed that the fracture pattern was the same regardless of the crack thickness and the bond stress was measured similarly.
