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.

This article introduces a commercialised energy-saving cement made by co-grinding OPC clinker with steelmaking slag (steel-slag) and blastfurnace slag that represents a different approach to cutting greenhouse-gas (GHG) emission footprints and conserving natural resources. The cement uses only 15-30% of OPC clinker, 30 …

Porous slag blocks (1 m3) were produced by carbonation of steelmaking slag over a period of 12 days. The compressive strength and bulk density of the blocks were 18·4 ± 3·3 MPa and 2·4 g/cm3, respectively. To make a large block, the optimum amount of water and bulk density of the compact were 5·3–6·3 mass% and 2·30–2·37 …

Steelmaking slag has been extensively studied as aggregate for cement-based composites. Because of the distinct properties of this residue, traditional mix design methods are not suitable to determine its target compressive strength, which hinders research studies and compromises its use on a large scale.
