In this study, the effect of the depth of concrete cover and the curing time on the concrete-reinforcement bond strength in concretes with eighth different compressive strength levels was investigated. Eighth different concrete mixtures were produced. 150 mm cubic specimens were cast from these mixtures. Deformed reinforcements of 14 mm diameter were embedded at a depth of 70 mm into specimens. Three different depth of the concrete cover were selected. The pull out loads, compressive strength, splitting tensile strength and modulus of elasticity of the specimens were determined.
