Slag - Wikipedia

Slag is drawn off the furnace just before the molten steel is poured into ladles for ingotting. Ferrous and non-ferrous smelting processes produce different slags. The smelting of copper, lead and bauxite in non-ferrous smelting, for instance, is designed to remove the iron and silica that often occurs with those ores, and separates them as ...

Steel Slag Usage in Cement | Industrial Efficiency ...

About 100 – 200 kg of BOF slag is generated per ton of liquid steel. This material is often used in projects like road construction, but this route provides little energy efficiency gains. Steel slag can also be used in the cement clinker manufacturing process. The result is an increase in clinker production of up to 15% with no net increase in CO2 emissions.

Reducing Permeability - Slag Cement

When slag cement is used as part of the cementitious material in a concrete mixture, it reacts with Ca(OH) 2 to form additional CSH, which in turn lowers the permeability of the concrete. Generally, the higher the percentage of slag cement in a concrete mixture, the lower the permeability of the concrete.
