摘　　要：再生骨料混凝土(RAC)是一种绿色低碳建材,对促进混凝土行业低碳化发展具有重要的意义。首先从废弃混凝土再生利用率、与RAC相关的技术规程、政策法规及RAC工程实践4个方面对比分析了国内外RAC的应用现状;然后介绍了RAC在材料性能、结构构件性能及环境经济性方面的研究进展,指出RAC在技术上可行且环境效益突出;最后展望了绿色高性能再生混凝土(GHPRC)的应用前景。对RAC的理论研究已日趋成熟,今后应着重研究其在工程应用中涉及的安全性、可靠性及成本等问题。Recycled aggregate concrete is a green low-carbon building material. It can promote the low-carbon development of concrete industry. Firstly, the RAC application at home and abroad from utilization of waste concrete, technical regulations, policies, regulations and practices related to RAC,were analyzed comparatively. Se condly, the RAC advancement of properties, structural performance, environmental effect and cost, were introduced . It shows that RAC has technical easiblility and great environmental benefits. Finally, green high performance recycled concrete was prospected. Theoretical research on RAC has matured, and future research should focus on engineering applica- tion, such as security, reliability, and cost, etc.
