再生混凝土是目前建筑垃圾处理技术研究及推广的主要方向，并作为一种新型建筑材料，改变了国家以往对建筑垃圾填埋的处理方式，节约了土地资源，减少山砂、石开采，符合国家绿色、低碳、可持续发展战略。再生骨料孔隙率高于天然骨料，能显著影响混凝土的耐久性，再生混凝土自问世以来其耐久性能便备受关注。主要综述了再生混凝土抗碳化性能、抗冻性能、抗氯离子渗透性能及介质侵蚀等耐久性的研究现状，并对现已建立的耐久性相关模型进行了简单介绍。
Recycled aggregate concrete is the main direction and promotion of construction waste disposal tech-nology which as a new building material saves land resources,reduces the mountain of sand,stone mining.It is con-sistent with national green,low-carbon sustainable development strategies.Because the high porosity of recycled ag-gregate affects the durability of concrete more significantly than natural aggregate,the durability of recycled aggregate concrete draws a lot of attention.Through the study of the domestic and foreign references,this paper mainly reviews the research status of carbonation resistance,frost resistance,resistance to chloride ion penetration and media erosion of recycled aggregate concrete,meanwhile gives a brief introduction of durability correlation models established.
