Regen GGBS

What is Regen?

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. Regen conforms to BS EN 15167-1 “Ground Granulated Blast furnace Slag for use in concrete, mortar and grout” and is available throughout the UK, accompanied by a full technical and logistical support package.

Appearance

Regen provides a superior, lighter-coloured finish than concrete made using Portland cement-only mixes.

In particular, Regen enables:

  • A lighter-coloured concrete
  • Greater reflectivity, providing better visibility and therefore safety in dark environments
  • Reduced efflorescence

Because of the near-white colour, Regen can be used as a replacement for White cement, with only a minimal difference in whiteness. However, for architectural applications where brightness is a critical factor, it is still recommended to use White cement wherever practical.
