摘要

通过对不同锈蚀程度的钢筋与再生混凝土试件的拔出试验,得到锈蚀程度对钢筋与再生混凝土黏结性能的影响,同时对比了同等条件下钢筋与普通混凝土黏结性能的变化规律。通过试验得到以下结果:再生混凝土及普通混凝土试件的黏结性能在锈蚀作用的影响下均表现出不同程度的下降;钢筋锈蚀程度对再生混凝土黏结性能的影响作用小于普通混凝土;锈蚀后,再生混凝土试件的残余荷载高于普通混凝土试件。
        Through the pull-out test,the influence of corrosion on the bonding performance between bar and recycled concrete is obtained.Meanwhile,the change rule of bonding performance between bar and ordinary concrete under the same condition is compared.The following results were obtained:the bonding properties of recycled concrete and ordinary concrete specimens decreased under corrosion.The effect of the corrosion degree of steel bar on the bonding performance of recycled concrete is less than that of ordinary concrete.After corrosion,the residual load of recycled concrete specimen is higher than that of ordinary concrete specimen.
