This study investigated the effect of recycled coarse aggregate satisfied the MOCTs quality criterion on bonding stress in concrete. Main parameter considered included the substitution ratio of recycled aggregate, 0%, 10%, 20%, 30%, 40% and 50%. The test results indicated that the bonding stress of specimens used recycled aggregate by maximum 50% higher than plain concrete. From the test, when the substitution ratio of recycled coarse aggregate decreased about 10% in concrete compressive strength and bonding-stress, but the predicted bonding-stress by design code as ACI, CEB-FIP was conservative.
