摘要：从黏附砂浆、界面过渡区、裂纹损伤这3个方面介绍了建筑垃圾再生骨料（RCA）的特性，并分析了RCA对混凝土性能的影响。基于此，总结了近年来常见的建筑垃圾再生骨料改性方法，如酸化改性、化学浆液改性、纳米技术改性、碳化改性、微生物矿化改性、复合技术改性等，并分析了其改性机理，可为建筑垃圾资源化利用和再生骨料的性能提升研究提供参考。 Abstract: The characteristics of construction waste recycled aggregates(RCA) from the aspects of adhesive mortar, interface transition zone, and crack damage are introduced, and the influence of RCA on performance of concrete is analyzed. Based on this. The common modification methods of construction waste recycled aggregates in recent years are summarized, such as acidification modification, chemical slurry modification, nanotechnology modification, carbonization modification, microbial mineralization modification, composite technology modification, etc. The modification mechanism is analyzed, which can provide a reference for the resource utilization of construction waste and the performance improvement of recycled aggregates.
