In this paper, quality of concrete used in reinforced concrete walls (RC-walls) in different phases from production to placing stage are studied. For this purpose, nine different RC-walls were cast which have different properties. Two different concrete classes were used in experiments. Some core specimens were drilled from RC-wall 14 and 28 days after the concrete is cast. Compressive test results of these core specimens are compared to control specimens which are cured in laboratory conditions. Factors such as concrete classes, mold type, placing with vibrator, curing are evaluated separately in every concrete specimen and results are discussed. It is found that compressive strength and hardness of the cores extracted from RC-walls with low reinforcement bar spacing and air cured is lower than that of core specimens from RC-wall which have normal reinforcement bar spacing, vibrated and wet cured specimens.
