摘　　要：为了解决机制砂的添加造成路面机制砂水泥混凝土耐磨性显著下降的问题,本文以丙聚丙烯酸酯乳液(NBS丙乳)和羧基丁苯胶乳液(X SBRL)作为试验聚合物制作水泥混凝土试件,并对混凝土试件进行抗压强度试验、抗折强度试验以及耐磨试验。试验表明,聚合物的添加能够提高混凝土的抗折性能和耐磨性能,但是在一定程度上会降低抗压强度,因此在实际工程中依据工程要求选择合适的聚合物。In order to solve the problem that the addition of mechanism sand causes a significant decrease in wear resistance of pavement sand cement concrete,this paper makes cement concrete test parts as a test polymer with propylene polyacrylic emulsion(NBS propylene milk)and xSBRL(XSBRL)liquid as a test polymer,and carries on the pressure strength test on the concrete test.F old-resistant strength test and wear test.The experiment shows that the addition of polymer can improve the anti-fold performance and wear resistance of concrete,but to a certain extent,it will reduce the pressure strength,so in the actual engineering according to the engineering requirem ents to choose the appropriate polymer.
