摘要:

硅酸钙板主流工艺的蒸压养护环节能耗高、碳排放占比高,CO2养护技术能够同时实现硅酸钙基材料界面强化与CO2封存,但目前该技术在硅酸钙板领域的应用缺乏系统总结,制约了其工艺优化与工程推广。本文系统综述CO2养护硅酸钙板的研究进展:首先阐述蒸压养护工艺关键步骤及制品常见缺陷,进而阐明CO2养护中硅酸钙矿物的碳化过程、产物特性与多尺度机理。在此基础上,从力学性能和碳封存效率等方面对比CO2养护与蒸压养护板的性能,分析该技术的优势与局限。最后展望工艺参数协同优化及纤维-基体界面定向调控碳化机理等未来研究方向。研究表明,CO2养护通过产物填充孔隙和界面增强来提升材料性能,并实现CO2稳定封存,但仍存在养护效率偏低、长期稳定性不足等挑战。本文可为硅酸钙板绿色制造升级与建材行业降碳路径提供参考与实践依据。

Abstract:

The autoclaved curing process, a mainstream step in calcium silicate board production, is characterized by high energy consumption and a significant proportion of carbon emissions. Meanwhile, CO2 curing technology offers a dual advantage: it simultaneously enhances the interfacial properties of calcium silicate-based materials and enables CO2 sequestration. However, the lack of a systematic summary of this technology’s application in the calcium silicate board field currently hinders its process optimization and engineering promotion. This work provides a systematic review of the research progress of CO2-cured calcium silicate boards. It begins by outlining the key steps of the autoclaved curing process and the common defects in the resulting products. It then elucidates the carbonation process of calcium silicate minerals during CO2 curing, along with the characteristics of the reaction products and the multi-scale mechanisms involved. Building on this foundation, the performance of CO2-cured boards is compared with that of autoclave-cured boards in terms of mechanical properties and CO2 sequestration efficiency, analyzing the technology's advantages and limitations. Finally, future research directions are proposed, including the synergistic optimization of process parameters and the targeted regulation of carbonation mechanisms at the fiber-matrix interface. The study indicates that CO2 curing enhances material performance through pore filling by products and interface strengthening, while achieving stable CO2 sequestration. Nevertheless, challenges such as low curing efficiency and insufficient long-term stability still exist. This review can provide theoretical reference and practical basis for the green manufacturing upgrade of calcium silicate boards and decarbonization pathways of the construction materials industry.
