The experiments which were conducted in this research evaluate the influence of concrete mix using granite as aggregate on the longitudinal splitting behavior between steel and concrete. For these experiments three prisms were cast at a time having different compressive strength of concrete 4500psi and 6000psi and different cross sections. Additionally, four different wires type were used in these experiments in order to evaluate the influence of all variables on the bond between steel and concrete which is highly important for transferring the stresses between the two materials.
