摘　　要：当前,由于橡胶在世界上的广泛使用,导致了大量的橡胶废料。从经济和生态优势来看,回收橡胶废料制造新材料(比如橡胶颗粒在水泥砂浆和混凝土的运用)是解决这个问题的最佳方案。先前已经有大量的研究已经进行或正在评估包含各种掺量的橡胶颗粒水泥复合材料的性能。本综述摘录了国内外对废旧橡胶混凝土的耐久性研究成果,全面分析了废旧橡胶混凝土在抗冻性、抗渗性、抗碳化性、抗氯离子渗透性、抗酸碱腐蚀性等特点,并集中概括了其中的改性原理。Recently, the rubber can be found its widespread application all over the world, which has led to huge quantities of rubber waste. Recycling of rubber waste to produce new materials like cement mortar and concrete appears as one of the best solutions for disposing of that in terms of its economic and ecological advantages. There have been research performed or are under way to evaluate the properties of cement-composites containing different proportions of rubber particles. This review summarizes the research on concrete containing waste rubber at home and abroad in terms of the durability and analyze rubber concrete on the characteristics of freezing resistance, impermeability, carbonation resistance, chloride ion penetration resistance, alkali corrosion resistance etc. conpresensively as well as summarize the corre- sponding modification mechanisms intensively.
