This study focused on how aging affected the properties of steel slag. Steel slag was treated using hydrothermal aging and pressure steaming aging techniques to improve its bulk stability. Physical and mechanical characteristics, alkalinity, and mineral constituents, as well as micromorphology of steel slag, were investigated. The results demonstrated that water absorption, crushing value, and abrasion value were all decreased by hydrothermal and pressure steam aging. The f-CaO particle size, total slag hydration time, and slag alkalinity were all lowered by two aging procedures. At 90 degrees...
