| 摘 要： | 对比试验显示，花岗岩表面涂一层硅烷偶联剂溶液后，再浇水泥砂浆，能显著提高两者界面层的粘结强度．在此基础上结合硅烷偶联剂化学，初步探讨了偶联剂在水泥浆／花岗岩界面层形成化学键的机理及其检验问题，并说明用偶联剂大幅度改善新老混凝土修补界面层性能的可行性．

| Abstract: | An experimental research showed that coating granite surface by using silane coupling agent could significantly increase the bond strength of cement paste-granite interfacial layer. Based on silane coupling chemistry, the mechanism and inspection of silane coupling agent creating a chemical bond between cement paste/granite interfaces were investigated. It was indicated that new and old concrete repair interfacial layer properties was improved by using silane coupling agent. |

| Keywords: | cement paste-granite bond interfacial layer silane coupling agent chemical bond |
