摘　　要：将废旧汽车轮胎经过处理后得到的橡胶细颗粒取代部分骨料配制成橡胶集料混凝土,采用ASTM C 1202-97法对5组不同橡胶掺量的混凝土进行抗氯离子渗透性研究,结果表明,橡胶集料混凝土具有很低的氯离子渗透性,28d电量值均小于1000C,且导电量随橡胶掺量增加而减少。Crumb Rubber Concrete （CRC）, also called Rubberized Concrete, is developed by replacing a portion of aggregates with shredded worn-out automobile tire particles in Portland cement concrete. The chloride ion penetration in CRC with different amount of rubber particles up to 100kg/m^3 in volume, is investigated by following the ASTM C 1202 - 97 method. The results show that the charge passed through CRC is typically in the order of 1000C, and is considered very low according to ASTM C 1202 - 97 standard. It is noticed that the charge decreases as the crumb rubber increased in CRC.
