Abstract

This review by Working Group 1 of the RILEM TC 309-MCP discusses recent advances in the beneficial carbonation treatment of recycled concrete aggregates (RCA). The impact of carbonation on RCA properties as well as the microstructure and performance of concrete and other construction materials made thereof is critically reviewed. The increasing focus on environmentally friendly building practices has led to a greater interest in the CO₂ uptake associated with carbonation processing. Furthermore, emphasis is placed on the importance of adopting tailored strategies to optimise the carbonation process based on the quality and type of RCA. Evidence in the literature highlights the beneficiation potential of carbonation processing in improving RCA properties and performance, which translates in variable degrees of enhancement of the performance of concrete or otheinitial; position: relative; float: left; top: 0px; left: 0px; z-index: 1 !important; pointer-events: none;"/>er applications made thereof. The review concludes that, to date, significant techno-economic challenges remain to be addressed to improve the competitiveness of the technology, notably in terms of upscaling and refining life cycle assessment data.

建筑中的碳化再生混凝土骨料：RILEM TC 309-MCP确定的潜力和瓶颈

本综述由RILEM TC 309-MCP第一工作组讨论了再生混凝土骨料（RCA）有益碳化处理的最新进展。碳酸化对RCA性能的影响以及混凝土和其他建筑材料的微观结构和性能进行了严格的审查。对环境友好型建筑实践的日益关注导致了对与碳化处理相关的二氧化碳吸收的更大兴趣。此外，重点放在了采用量身定制的战略，以优化碳酸化过程的基础上的质量和类型的RCA的重要性。文献中的证据强调了碳化加工在改善RCA性能和性能方面的选矿潜力，这转化为不同程度的混凝土或其他初始性能的增强；位置:相对;浮:左;上图:0 px;左:0 px;z指数：1 !重要；指针事件：none "/>；该审查的结论是，到目前为止，仍然需要解决重大的技术经济挑战，以提高技术的竞争力，特别是在升级和完善生命周期评估数据方面。
