Abstract

This paper investigates about the Bond-Slip behaviour of steel rebars in reinforced concrete for Plain and Ribbed reinforcing bars. Bond strength is influenced by the rib pattern of the bar and RILEM suggested some recommendations to increase the bond strength of the concrete. Two grades of concrete M25 and M30 were casted. A total of 20 specimens were casted using 25mm bar. Twelve cube specimens were casted without reinforcement and casting done in horizontal position and Eight flexure beams were casted. The bond stress-slip response was studied. Pullout test was used to test the cube specimens. Graphical comparison were done between the Load vs Slip and Load vs Displacement for RILEM standards. Slip was measured using LVDT at both ends. Ribbed bars showed better bond strength compared to plain bars and bond strength obtained from both tests produced same results.
