| 中文摘要: |
| 建筑垃圾资源化利用是推动“无废城市”建设的重要举措。包含废弃混凝土、砖混及装修垃圾在内的建筑垃圾再生骨料具有吸水率高、压碎值大等缺陷，是建筑垃圾再生骨料资源化利用的难点。本文从分别从工作性能、力学性能、耐久性能等方面总结了建筑垃圾再生骨料应用于再生混凝土的研究进展，阐述了强化再生骨料的几种途径与机理。通过分析建筑垃圾再生骨料再利用的研究现状，本文提出了现阶段再生骨料高值化研究与应用的方向，为处理建筑再生骨料提供新思路。 |

| The resource utilization of construction waste is an important measure to promote the construction of ' no waste city '. The construction waste recycled aggregate including waste concrete, brick concrete and decoration waste has the defects of high water absorption and large crushing value, which is the difficulty of resource utilization of construction waste recycled aggregate. This paper summarizes the research progress of construction waste recycled aggregate applied to recycled concrete from the aspects of working performance, mechanical properties and durability, and expounds several ways and mechanisms of strengthening recycled aggregate. By analyzing the research status of recycled aggregate reuse of construction waste, this paper puts forward the direction of high value research and application of recycled aggregate at the present stage, and provides new ideas for dealing with recycled aggregate of construction waste. |
