摘要：
According to Standard Methods for Testing of Concrete Structures (GB50152-92), a pull-out test was designed, and the load vs slip curves between recycled concrete with different recycled coarse aggregate replacement percentages and different types of rebars were recorded. Based on the analysis of the test results, the bond strength between recycled concrete and rebars was investigated. Regression analysis on the test results was performed and the bond stress vs slip relationship was proposed. Moreover, the anchorage length of rebars in recycled concrete was preliminarily suggested.
