摘要
再生骨料碳化处理不仅可改善再生骨料的物理特性,而且可吸收温室气体CO2,是一种环境友好型改性方法。介绍了再生骨料加速碳化的机理和方法;总结了再生骨料碳化后的物理性能和再生骨料碳化混凝土的工作性能、力学性能和耐久性能;最后,进一步指出了再生骨料碳化改性尚待研究的主要问题。已有文献表明再生骨料碳化处理是改善再生骨料及再生混凝土性能可行且有效的方法。
The carbonation treatment of recycled aggregate （RA） enhances its physical properties and sequestrates greenhouse gas CO 2, which is an environmental friendly approach. Firstly, the mechanism and methods of accelerated carbonation of recycled aggregate are introduced. Secondly, the physical properties of recycled aggregate after carbonation and the workability, mechanical properties and durability of recycled aggregate concrete （RAC） incorporating carbonated recycled aggregates are summarized. Finally, the main problems that need to be further studied in the carbonization modification of recycled aggregate are proposed. It suggests that carbonation treatment is an efficient and feasible method for improving the mechanical properties and durability of RA and RAC.
