摘　　要：研究了可再分散性乳胶粉对混凝土结构修补砂浆的物理和力学性能的影响。试验结果表明胶粉对新拌砂浆的物理性能和硬化砂浆的力学性能有很大的影响;胶粉在较低掺量时修补砂浆工作性显著改善。抗压强度明显增大且抗折强度和拉伸黏接强度也有不同程度的提高。It studied the effects of redispersible emulsion powder on the physical properties and mechanical properties of concrete structural repair mortar.Test results show that redispersible emulsion powder has significant effects on the physical properties of fresh mortar and mechanical properties of hardened mortar.When redispersible emulsion powder in a lower dosage,the workability of fresh mortar and the compressive strength of hardened mortar had been significantly improved and the flexural strength and tensile bond strength also had been increased in different degrees.
