摘　　要：通过50次冻融循环的套筒植筋粘接强度试验,研究了冻融循环对钢筋与结构胶之间界面粘接性能的影响。试验结果表明:与自然状态下养护的结构胶套筒粘接强度相比,经过冻融循环试验后的套筒结构胶的粘接强度仅降低了5.85%;结构胶具有良好的粘接耐久性。The influences of freeze-thaw cycles on bonding performance of interface between rebar and structure adhesive were investigated by bonding strength experiment after 50 freeze-thaw cycles for bonding rebar specimens in metal tube.The experiment results showed that the bonding strength of structure adhesive in metal tube after freeze-thaw cycles experiment was only 5.85% less than after standard curing in natural atmosphere.The structure adhesive had well bonding durability.
