Abstract: Experiment was carried out to study the influences of rebar corrosion ratios, recycled aggregate replacement ratios, and recycled concrete strengths on the bond-slip constitutive behavior of recycled concrete with corroded rebars. In order to obtain the curves of load-slippage between recycled concrete and different corrosions rebar as well as rebar strain along anchorage length, 23 specimens were investigated using pull-out test, in which a quick electricity method for rebar corrosion and inner-embedded strain foils approach were used in the laboratory test. Based on the experimental results, the bond stress and slippages along the anchorage length under different corrosions are calculated. The mechanisms of the stress transmission and bond position function difference, before and after rebar corrosion, are then analyzed. The bond position function and bond-slip constitutive model of corroded rebar and recycled concrete are proposed, which is expected to provide reference for finite element analysis.
