Enhancement of the cementitious properties of steelmaking slag
Abstract. The overall objective of this work was to determine whether steel slag might be processed into a sufficiently cementitious material to allow it to be recycled as an additive to ordinary Portland cement clinker. Steel slag has limited cementitious properties due to both a lack of tricalcium silicate and the presence of wustite solid ...

Calcium leaching from waste steelmaking slag
The slag produced in the highest volumes is blast furnace slag, which is generally fully utilised as both an aggregate for road construction and as an additive in Portland cement (Hiltunen and Hiltunen, 2004). The second most produced slag is basic oxygen steelmaking (BOS) slag from the Linz-Donawitz process.

3.1 Cooling of the steelmaking slag As steelmaking slag is formed, it is in a molten or red-hot state at a temperature of 1,300-1,700°C. Therefore, steelmaking slag must be immediately subjected to the cooling process upon removal. Ordinarily, this is performed in a cooling yard by air cooling and moderate water sprinkling.
