Prolonged grinding aggregated the particles of steel slag and reduced the surface area. • Grinding disorders the crystal structure of C 2 S, C 7 A 12, Ca(OH) 2, but crystallizes CaO.. Carbonates precipitation is the rate limit step of steel slag cured at 20 °C and 20% CO 2.. Grinding increases the strength of carbonated steel slag by enhancing its hydration rate.

Iron and steel slags are coproducts of iron and steel manufacturing. In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the reducing agent. The iron ore is a mixture of iron oxides, silica, and alumina. From this and the added fluxing agents molten slag and ...

The steel slag produced during the primary stage of steel production is referred to as furnace slag or tap slag. This is the major source of steel slag aggregate. After being tapped from the furnace, the molten steel is transferred in a ladle for further refining to remove additional impurities still contained within the steel.
