摘　　要：采用橡胶粉代替部分细骨料制备橡胶混凝土,并对其性能展开研究。结果表明:虽然橡胶粉的加入会导致橡胶混凝土的力学性能降低,但适量的橡胶粉有利于提高混凝土的耐磨性能以及抗冻性能。其中,橡胶混凝土获得最优耐磨性能与抗冻性能的最佳橡胶粉掺量分别为5%和10%。Rubber concrete was prepared by using rubber powder instead of some fine aggregate,and its properties were studied.The results show that although the addition of rubber powder will reduce the mechanical properties of rubberized concrete,an appropriate amount of rubber powder is beneficial to improve the wear resistance and frost resistance of concrete.Among them,the optimum amount of rubber powder for rubber concrete to obtain the best wear resistance and frost resistance is 5%and 10%,respectively.

关 键 词：橡胶混凝土 橡胶粉 耐磨性 抗冻性
