摘要:

全球温室效应的日益加剧使矿物固碳技术在水泥行业中的应用受到广泛关注。鉴于硅酸盐水泥生产过程中高能耗的挑战,使用经过处理的钙基工业固体废弃物作为替代品已成为一种更具可持续性的选择。以粉煤灰、钢渣、电石渣、副产石膏及水泥基建筑垃圾等典型钙基工业固体废物为代表,根据来源、组成成分、物理化学性质综述了钙基工业固体废弃物的CO2固碳机理、吸附潜力及产品的应用前景和附加价值,详细阐述了钙基工业固体废弃物碳化反应条件的优化、固碳副产品的利用方式,以及对混凝土工作性和长期使用活性方面的潜在影响。在未来的研究中,应集中于持续优化碳化反应动力学参数、开发高效的协同活化工艺以提高工业固废在建材产品中的替代比例,以工业固废的大规模资源化利用与水泥行业的低碳转型为目标,为实现全球“碳中和”目标提供技术支持与经济保障。

Abstract:

The intensifying global greenhouse effect has drawn significant attention to the application of mineral carbonation technology in the cement industry.In view of the high energy consumption associated with Portland cement production,the utilization of processed calcium-based industrial solid wastes as substitutes has emerged as a more sustainable solution.In this paper,typical calcium-based industrial solid wastes such as fly ash,steel slag,calcium carbide slag,by-product gypsum and cement-based construction waste were taken as representatives.The CO2 sequestration mechanism,adsorption potential,application prospect and added value of calcium-based industrial solid wastes were reviewed according to the source,composition and physicochemical properties.Furthermore,it provided a detailed discussion on the optimization of carbonation reaction conditions,the utilization of carbonated byproducts,and the potential impact on concrete workability and long-term performance activity.Future research should focus on continuously optimizing the kinetic parameters of carbonation reactions and developing efficient synergistic activation processes to enhance the substitution ratio of industrial solid wastes in construction materials.With the aim of achieving large-scale resource utilization of industrial solid wastes and facilitating the low-carbon transition of the cement industry,these efforts would provide technical support and economic guarantees for achieving global carbon neutrality.

Key words: CO2 adsorption, industrial solid waste, mineral carbonation, supplementary cementitious materials
