This paper investigates the bond strength between concrete and steel specimens which are bonded together to form a composite cylinder and observe the failure pattern and type of failure. The Slant Shear Test method, by ASTM C882 is used to check the bond strength between steel and concrete specimen. The steel and concrete specimens are bonded together on a slant elliptical plane at a 30° angle from vertical using epoxy based bonding agent. It is assumed that if the failure occurs on slant surface then the bond strength we obtain is true bond strength but on performing test the results shows that the bond strength obtained is not true bond strength i.e. failure don’t occur on slant surface. The bond strength obtained is apparent bond strength. Thus, the slant shear test does not always provide true bond strength between the samples which are bonded together.
