摘要
通过碳纤维从自密实混凝土中的拔出试验,分析纤维长度和浸胶处理以及预应力对粘结性能的影响规律。试验结果表明:随纤维埋长增大,纤维的最大拉拔力不断增大,用环氧树脂浸渍碳纤维并对碳纤维施加预应力能提高粘结性能。
The influence rules of some factors, such as initial bond length of fiber, surface impregnating treatment of fiber, prestressing force on bond performance were studied on the basis of pull-out tests . The tests results show that with initial bond length increasing, the maximum pull force increases and carbon fiber epoxy impregnating and prestresssing can improve the bond performance between carbon fiber and concrete.
