  The bond properties between concrete and reinforcement are one of the factors that influence the crack properties of RC members. In this study, the compressive strength of concrete and the amount of bleeding were taken up as a factor that influences the bond properties between concrete and reinforcement. In order to investigate the influence of these factors, uniaxial tensile tests were carried out on RC members. As a result, it was found that the width of the maximum crack was influenced by the compressive strength of concrete and the influence of the amount of bleeding was comparatively small.
