摘　　要：研究了多种界面改性剂对橡胶集料与水泥基体的界面粘结强度以及橡胶集料水泥砂浆(CRM)强度的影响,探讨了界面改性剂在CRM中的作用机理。研究表明:界面改性剂能显著提高橡胶集料与水泥基体的界面粘结强度,增强CRM的力学性能,其中硅烷改性的苯丙乳液的效果最好。Several interfacial modifiers were used in this paper to improve the interface bonding strength between the crumb rubber and matrix and the whole strength of Crumb Rubber Mortar（CRM）.In addition,the function mechanisms of CRM by various interfacial modifiers were discussed.Based on the test results,interfacial modifiers could obviously improve the interface bonding strength between the crumb rubber and matrix and the whole strength of CRM.Silicone modified styrene-acryl ate-emulsion had the best effect.
