| 摘 要： | 当承受剪力和拉力时,粘结面是新老砼粘结结构受力的薄弱环节,使用合适的界面剂可以提高其粘结强度.本文采用新老砼粘结抗剪和粘结抗折试件,对几种界面剂的粘结强度进行了试验研究,得出使用不同界面剂时新老砼抗剪粘结强度和抗折粘结强度,分析了不同界面剂对新老砼粘结强度的影响,为实际工程中的应用提供参考.

| Abstract: | Bond plane is the tache of weakness for the new and old concrete bond structure when withstanding shear force and tension.Appropriate interfacial agent can improve bond strength.The shear resistance and tear resistance bond strength of new and old concrete for several interfacial agents were studied through experiments.Shear resistance bond strength and tear resistance bond strength of new and old concrete structure with different interfacial agents were gained,the effects of interfacial agents on bond strength of new and old concrete structure were analyzed.References for application of practical engineer were provided. |

| Keywords: | new and old concrete interfacial agent shear resistance strength tear resistance strength |
