| 摘 要： | 研究了在采用不同的界面剂处理下，水泥基砂浆加固混凝土构件的界面粘结抗剪强度，并进行了加固砂浆和基层混凝土的界面处的微观结构观测分析．研究结果表明：界面剂能提高界面粘结抗剪强度．超细水泥是一种很好的界面剂原材料．通过加入膨胀剂、硅灰和高效减水剂改性后的超细水泥界面剂，有很高的粘结抗剪强度．可再分散聚合物胶粉对界面粘结抗剪强度的改善效果很明显．

| Abstract: | This paper studied the interfacial adhesive shearing strength between the cement-based mortar and the concrete substrate, and investigated the microstructures of the interfacial zones between the new mortars and the old concretes.The results have shown that the interfacial agents can improve the interfacial adhesive shearing strength.Superfine cement suits were used as the interfacial agents.Superfine cement interfacial agents with expansion agents, silica fume and super plasticizer had high adhesive shearing strength.Re-disappeared polymer powders noticeably increased the adhesive shearing strength of cement-based interfacial agents. |

| Keywords: | superfine cement polymer powders adhesive shearing strength cement-based interfacial agents |
