摘   要：为研究锈蚀钢筋与再生混凝土的黏结性能，通过外加电流加速试验获得目标锈蚀率为1%的螺纹钢筋，将其分别与粗骨料取代率为0、20%、40%、60%、80%和100%的再生混凝土试块进行拉拔试验研究。结果表明，发现锈蚀钢筋与再生混凝土之间的黏结应力比未锈蚀的试块提前达到峰值.随着再生粗骨料取代率的增加，黏结应力先增大后减小，且当取代率为80%时，黏结应力达到峰值，锈蚀钢筋与再生混凝土之间的黏结应力-滑移曲线与普通混凝土的总体形状相似。

Abstract: In order to study the bonding properties between corroded reinforcement and recycled concrete，through external current accelerated test, the target corrosion rate is 1% rebar, the pull-out test of recycled aggregate concrete specimens with coarse aggregate replacement rate of 0, 20%, 40%, 60%, 80% and 100% respectively is carried out. It is found that the bond stress between corroded reinforcement and recycled concrete reaches the peak value earlier than that of the non corroded specimen. With the increase of the replacement rate of recycled coarse aggregate, the bond stress increases first and then decreases. When the replacement rate of coarse aggregate is 80%, the bonding strength of recycled concrete reaches the maximum value. The bond stress slip curve between corroded reinforcement and recycled concrete is similar to the general shape of ordinary concrete.
