GGBS; sustainable alternative to Portland Cement | LKAB ...
As a byproduct of existing industrial processes, GGBS is even more sustainable than many other cement substitutes such as fly ash. Our GGBS conforms to BS EN 151671. This is the British standard for the use of Ground Granulated Blast furnace Slag in concrete, mortar and grout. GGBS counts fully towards the cement content of concrete mixes.
