Superfines Cement Additive
Superfines Cement Additive

A high-performance cement additive, derived from BOS slag, with lower CO2 emissions.


Our Superfines Cement Additive is manufactured from BOS steel slag and can be used in both standard and high-performing concrete, when prepared accordingly. When using slag as an additive in the kiln, cement manufacturers can produce a product which has the same properties as traditional cement, but with the advantage of a lower CO2 emissions. The reduction in emissions lowers the carbon footprint of buildings which are built using slag cement.
