摘　　要：超强韧性混凝土(PP ECC)作为一种新型建筑材料,具有优良的力学性能,可用于普通混凝土路面和混凝土结构的修补工作。基于研究超强韧性混凝土修补混凝土的常用界面处理方法,包括刮削、磨砂、钻孔和凹槽,通过剪切试验和拉伸试验,对比分析其性能,试验结果表明磨砂是修补界面可采用的较优的方式。As a kind of new building material,PP ECChas excellent mechanical properties,which can be used for the repair of ordinary concrete pavement and concrete structure.In order to study the common interface treatment methodsof PP ECC to repair concrete,including scraping,sanding,drilling and groove,its properties are compared and analyzed through shear test and tensile test.The test results show that sanding is a better way to repair the interface.
