Hanson Regen Ground Granulated Blast furnace Slag (GGBS) is a cement substitute, manufactured from a by-product of the iron-making industry. Using one tonne of Regen in concrete reduces the embodied CO2 by around 900kg, compared to using one tonne of Portland Cement, and also increases its durability. Regen is more sustainable than other cement substitutes such as Fly Ash.

In the UK, GGBS is usually supplied as a separate component for concrete and is added at the concrete mixer. It can replace 70 per cent or more of the Portland cement. In British Standards GGBS is referred to as an ‘addition’ and counts fully towards the cement content in concrete.
