摘　　要：随着“双碳”目标的推进,循环流化床(circulating fluidized bed, CFB)灰渣因产生量大、组分复杂及处理需求迫切,成为固废资源化利用的重要研究方向。本文综述了CFB灰渣的组成与特性,聚焦其膨胀特性和疏松结构,总结了CFB灰渣在水泥基材料、地质聚合物、道路基层材料、气凝胶制备及沸石制备等领域的低碳化应用现状和高附加值利用研究。研究表明,CFB灰渣在提升水泥基材料力学性能、优化微观结构及改善耐久性能方面具有显著优势。尽管存在高硫高钙引发的膨胀等问题,但通过物理或化学改性技术,CFB灰渣作为地质聚合物和高附加值功能材料的潜力逐渐被挖掘,应用价值显著提升。在未来,研究者应加强改性技术的研发与资源化路径的探索,推动CFB灰渣在低碳循环经济中的应用,为实现工业固废的可持续利用提供理论基础和技术支撑。With the advancement of the“Dual Carbon”strategy,circulating fluidized bed(CFB)ash has become an important research direction for solid waste resource utilization due to its large amount of production,complex component and urgent treatment needs.This paper reviews the composition and characteristics of CFB ash,focusing on its expansion characteristics and loose structure,and summarizes the low-carbon application status and high value-added utilization research of CFB ash in the fields of cement-based materials,geopolymers,road base materials,aerogel preparation and zeolite preparation.The research shows that CFB ash has significant advantages in improving the mechanical properties of cement-based materials,optimizing microstructure and improving durability.Although there are questions such as expansion caused by high sulfur content and high calcium content,the potential of CFB ash as geopolymer and high value-added functional material is gradually explored through physical or chemical modification technology,and the application value can be significantly improved.In the future,researchers should strengthen the research and development of modification technology and the exploration of resource recycling path,promote the application of CFB ash in low-carbon circular economy,and provide theoretical basis and technical support for the sustainable utilization of industrial solid waste.
