Abstract
To meet the requirement of machine-made sand application in concrete structures, experimental studies were carried out on the bond of plain steel bar with Machine-made Sand Concrete (MSC) by the central pull-out test method. Three specimens were cast as one group, 14 groups were tested considering the influence of concrete strength, bond length and stone powder content in machine-made sand. Based on the experimental research, the characteristic values of bond-slip curve such as the initial-slip and ultimate bond stresses with corresponding slips are statistically analyzed, the bond-slip constitutive relations between plain steel bar and MSC were obtained.
