Abstract: Based on suggestions of the "Standard Methods for Testing of Concrete Structures" (GB50152-92), two water-cement ratios, five replacement percentage of recycled coarse aggregates and four types of steel bars were considered as the main factors, 120 pull-out tests were carried out in order to investigate the bond-slip behavior between recycled aggregate concrete and steel bars. Based on the analysis of the test results, the influence of different water-cement ratios, replacement percentages and the steel bar types on the bond strength between the recycled aggregate concrete and steel bars were investigated. At the same time, the bond-slip curves between recycled aggregate concrete with different recycled aggregate replacement percentages and different types of bars were recorded. Finally, using regression analysis, a three-subsection analytical model that can express the empirical bond-slip relation between recycled aggregate concrete and steel bars was established.
