摘　　要：再生骨料混凝土是混凝土可持续发展的必然归属。简述了RAC研究的历史起源,从材料、构件、结构三个层次,总结了RAC研究的主要进展,认为RAC的发展趋势应是绿色高性能再生混凝土(Green High Performance Recycled Concrete,GHPRC)。给出了GHPRC的完整定义,阐述了其绿色内涵。提出了RAC向GHPRC发展尚需解决的两个关键科学问题:其一为经济合理的高品质再生骨料生产工艺;其二是在结构全寿命周期成本(Structural Life Cycle Cost,SLCC)理念下,GHPRC基于结构性能与环境性能的设计方法。Recycled aggregate concrete（RAC ） is the only way to go for concrete sustainable developmenLThe history headspring on RAC and main research progress from three levels,i.e.,materials,members and structures,were summarized.And development trend of RAC was drawn as green high performance recycled concrete（GHPRC ）.Then the integrated definition and green meaning were put forward.Two key problems worth to be studied afterward are put up.One is preparation technics of recycled aggregate with high-quality and reasonable cost.And another is design method of GHPRC based on structural performance and environmental performance with the guide line of structural life cycle cost （ SLCC ）.
