废旧橡胶混凝土的耐久性研究进展

Research progress on durability of waste rubber concrete

废旧橡胶混凝土是一种新型土木工程材料,与普通混凝土相比,其在材料韧性、抗冲击性能、耐久性能等方面均有不同程度提高,已经成为国内外学者研究的热点之一。综述了国内外近些年对废旧橡胶混凝土耐久性的研究成果,并重点对其在抗冻性、抗渗性、抗碳化性、抗氯离子渗透性、抗酸碱腐蚀性等方面的性能进行了总结分析,以期对国内外研究者有所借鉴并有力推动橡胶混凝土的广泛应用。

Waste rubber concrete is a new type of civil engineering materials,compared with ordinary concrete,its toughness in materials,impact resistance and durability were improved to varying degrees,has become one of the hot topics in the study of domestic and foreign scholars.Reviewed the recent years of waste rubber the research results of the durability of concrete,and the key to its in antifreeze,impermeability,carbonation resistance,resistance to chloride ion penetration,resistance to corrosion resistance to acid and alkali,and other aspects of the performance analysis are summarized,in order to make reference to the researchers at home and abroad and vigorously promote the wide application of rubber concrete.
