Ground Granulated Blast Furnace Slag (GGBS) offers great durability, reducing the likelihood of concrete thermal cracking, and it improves concrete’s resistance to damage from alkali-silica reaction, sulphates and chlorides.
Certification: BS EN 15167-1
By-product of existing industrial processes

Ground Granulated Blast Furnace Slag (GGBS) is a cement substitute that improves durability. It is a by-product of the iron-making industry. GGBS, used in a concrete mix, offers a good alternative to traditional Portland Cement.
The abbreviation GGBS or GGBFS are interchangeable and mean Ground Granulated Blast Furnace Slag.
As a by-product of existing industrial processes, GGBS offers less than 10% of the CO2 of CEM1*. Our products conform to BS EN 15167-1, the British standard for using Ground Granulated Blast furnace Slag in concrete, mortar, and grout.
GGBS counts fully towards the cement content of concrete mixes. Check our monthly conformity certificates to see the detailed chemical composition of our GGBS here.
