【摘要】 CO₂强化再生混凝土骨料不仅能改善再生混凝土骨料的性能还能减少二氧化碳的排放量。首先综述研究了CO₂强化再生混凝土骨料的机理和影响因素。然后分析了该方法对再生混凝土骨料和再生骨料混凝土的物理力学性能和耐久性能的影响,以及强化后再生混凝土骨料的微观结构变化。最后对未来进一步的研究提出了相应的建议。更多还原

【Abstract】 The CO2-treating recycled aggregates can not only enhance it′ s performance,but also reduce carbon dioxide emissions.Firstly,it reviews the reaction mechanisms,influencing factors,and then the physical performance,mechanical performance,durability and microstructure changes of recycled aggregates strengthened by CO2 are also analyzed,In the end,further laboratory and industrial research are also proposed.更多还原
