[0002] Cementitious materials have wide applications in urban construction, environmental management, mine restoration, and soil improvement. Cementitious materials made from mineral powder, steel slag, gypsum, and fly ash can not only effectively reduce cement usage and carbon emissions, thus contributing to the achievement of "dual carbon" goals, but also demonstrate superior performance in environmental management, mine restoration, and soil improvement applications.

[0003] Alkali-activated materials such as mineral powder, steel slag, gypsum, and fly ash are mostly industrial by-products. Typically, chemical and mining companies utilize waste heat from their factories to dry and crush these by-products into powdered finished products such as mineral powder, steel slag, gypsum, and fly ash. These powdered finished products are then purchased by cementitious material manufacturers, processed into cementitious materials, and then sold to designated application projects. This process requires two transportation steps, and the powdered materials also require specialized tank trucks, resulting in high transportation costs. Utility Model Content
