摘　　要：高性能复合砂浆钢筋网(HPF)是一种有效的加固混凝土结构的方法,文章对该方法加固的复合砂浆进行了抗压、抗拉性能等试验研究,介绍了该方法对混凝土受弯构件加固的试验影响和作用。试验结果表明,这种砂浆配合其界面剂的使用,很适合于目前用水泥复合砂浆钢筋网加固RC结构的工程应用。The compressive and tensile behavior of a kind of composite mortar which is used in highperformance ferrocement for strengthening RC structures was tested. Then the bending tensile test and shear test of specimens which were made of basic specimens and the composite mortar laminate with the interface bonded with adhesives of double groups of components were conducted. The strengthening effects of the specimens reinforced with high-performance ferrocement were tested and analyzed. The test results and the practice in strengthening of RC structures show that this kind of composite mortar and corresponding interfacial adhesives are quite applicable to current engineering and practice of strengthening RC structures with ferrocement.
