What is GGBS?
Ground Granulated Blast Furnace Slag (GGBS) is a cement substitute that improves durability and also the environmental credentials of concrete mixes. It is a by-product of the iron-making industry.
For every tonne of GGBS used in a concrete mix, the embodied CO2 levels are reduced by around 900 kg compared to the use of one tonne of traditional Portland Cement.
What is GGBFS?
The abbreviation GGBS or GGBFS are interchangeable and mean Ground Granulated Blast Furnace Slag.

As a by-product of existing industrial processes, GGBS is even more sustainable than many other cement substitutes such as fly ash. Our GGBS conforms to BS EN 15167-1. This is the British standard for the use of Ground Granulated Blast furnace Slag in concrete, mortar and grout.
