摘要
使用界面剂是提高新老混凝土的结合面黏结性能的重要手段,具有重要工程价值。本文分析了传统界面剂的优缺点,提出了一种新型环氧界面剂,并通过室内试验的方法验证了其有效性,同时探讨了老混凝土的龄期和强度对黏结性能的影响,可以为新型环氧界面剂的工程应用提供参考。
Interface agent is an important means to improve the bonding performance of new and old concrete interface.It has important engineering value.The advantages and disadvantages of traditional interface agent are analyzed in the paper.A novel epoxy interface agent is proposed in the paper.Its effectiveness is verified by the indoor test method.Meanwhile,the influence of age and strength of old concrete on the bonding performance is discussed,which can provide reference for engineering application of new epoxy interface agent.
