Bond-Slip Relation of Plain Steel Bar in Concrete with Machine-made Sand

摘要：

　　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.
