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.
