摘　　要：大量建筑垃圾的产生不仅会占用大面积的土地资源而且会对周边环境造成污染,发展再生混凝土为建筑垃圾资源化再利用提供了一个重要途径。然而,再生混凝土的实际工程应用受限于其长期耐久性问题。文中在分析国内外再生混凝土耐久性(抗冻性、抗氯离子渗透性、抗碳化能力、碱骨料反应)的基础上,总结其劣化原因,并提出改善措施。There is a large amount of construction waste,which will occupy a lot of land and cause environmental pollution.Preparing recycled concrete with is construction waste an important channel to consume construction waste.However,the practical application of recycled concrete is limited by its long-term durability.Based on the analysis of the durability(frost resistance,chloride ion penetration resistance,carbonation resistance and alkali aggregate reaction)of recycled concrete at home and abroad,this paper summarizes the deterioration reasons and proposes improvement measures.

关 键 词：再生混凝土 抗冻性 抗氯离子渗透性 抗碳化能力 碱骨料反应
