摘要
利用CO_(2)碳化强化基于废弃混凝土制备的再生骨料对其品质的提升、再利用以及碳减排有重要意义。分析再生骨料CO_(2)碳化强化的机理和强化后再生骨料在物理性能以及微观结构上的改善,对影响CO_(2)强化再生骨料的因素进行归纳分析,针对基于CO_(2)强化后再生骨料制备而成的再生骨料混凝土的物理力学性能、耐久性能和微观结构的改善进行对比分析,总结和归纳了研究进展和展望。
The accelerated carbonation on the properties of recycled concrete aggregates is important for the recycling of waste concrete,sequestration of CO_(2) and reduction of carbon emissions.In this review,the mechanism of accelerated carbonation on the recycled concrete aggregates and the physical properties and microstructure changes of recycled concrete aggregates enhanced by accelerated carbonation were introduced.Some factors for efficient CO_(2) treatment on the properties of recycled concrete aggregates were summarized.The physical properties,durability and microstructure improvement of recycled concrete containing CO_(2) treated recycled concrete aggregates were analyzed.In addition,the perspectives for future research were also proposed.
