钢渣碳化及其在建筑材料低碳制造中的应用

Carbon capture, utilization and storage(CCUS)technologies reduces the concentration of CO₂ in the atmosphere by capturing and converting CO₂, is one of the key technologies to achieve China’s climate goals and sustainable development. The research progress in the preparation of low-carbon building materials through accelerated carbonation of steel slag was summarized. The performance and enhancement mechanism of carbonized steel slag building products, as well as the hydration reactivity and hydration mechanism of carbonated steel slag supplementary cementitious materials, were systematically introduced. The application cases of accelerated carbonation techndogy in the industrial production of building materials were summarized, and the future development direction was prospected, in order to provide reference for the green transformation and sustainable development of the cement and concrete manufacturing industry.
