CO2养护硅酸钙板的研究进展
Research Progress of CO2 Curing for Calcium Silicate Board
摘要
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.关键词
