The experimental tests which were performed in this paper evaluate the effect of the concrete mixture using granite as aggregate on the longitudinal splitting behavior in prestressed concrete members. Three prisms having different edge distances were cast concurrently having different release strengths of concrete 4500-psi (31-MPa) and 6000-psi (41M-Pa). Furthermore, four different wires type were used in these experiments 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.
