摘　　要：通过对一种用聚合物纤维增强的复合砂浆进行了抗压、抗拉性能试验研究,对粘结面上涂刷有一种由水泥基复合的双组分无机界面剂的被连接试件进行了弯曲抗拉试验及剪切试验研究。破坏面的微观结构观测分析和宏观性能试验结果分析以及用于RC结构的加固实践均表明,这种砂浆配合其界面剂的使用很适合于目前用钢丝(筋)网水泥砂浆加固RC结构的工程应用。The compressive and tensile behavior of a composite mortar reinforced with polyp ropylene fiber is experimentally studied.Bending tensile test and shear test ar e coducted on samples made of basic specimens and the composite mortar layer, with the interface being bonded with a cement-based double-component adhesive .By observing the microscopic structures of broken sections and analyzing the macroscopic behavior of test results and the practice in strengthening of RC st ructures, it is verified that this type of composite mortar and the interfacial adhesive are applicable to strengthening RC structures with ferrocement.
