China has clearly stated its national goals of achieving carbon peak by 2030 and carbon neutrality by 2060. A systematic program centered around "energy conservation, carbon reduction, and green transformation" is being fully implemented across all industries. As a major carbon emitter, accounting for over 10% of national carbon emissions, the building materials industry urgently needs to embark on a path of green and high-quality development through process upgrades, equipment transformation, and intelligent manufacturing.

Mineral admixtures prepared from metallurgical solid wastes such as blast furnace slag, through ultrafine grinding and activation, exhibit excellent potential hydraulic activity and cementitious properties. As a high-quality mineral admixture, slag powder has been widely used in cement-based materials and high-performance concrete. It not only significantly improves the mechanical properties and durability of building materials, but also significantly reduces carbon emissions throughout the lifecycle of cement and concrete, providing a scalable and innovative path for promoting a green and low-carbon transformation in the building materials industry.
