Build sustainable construction projects with Regen GGBS

Still the best option for producing lower carbon concrete

Regen GGBS (Ground Granulated Blastfurnace Slag) is a sustainable cement alternative that enhances the durability of concrete while significantly reducing its carbon footprint.

Produced as a byproduct of the steel industry, Regen GGBS is no longer disposed of as waste but repurposed for use in concrete production. By replacing one tonne of CEM I (Portland) Cement with Regen, you can cut embodied CO2 by approximately 650kg, all while boosting concrete’s durability in certain applications.

More sustainable than other alternatives like Fly Ash, Regen GGBS is ideal for a wide range of construction projects. It not only strengthens and extends the lifespan of concrete but also supports eco-friendly building practices, even in demanding conditions.

Our high-performance GGBS meets industry standards and delivers superior results for residential, commercial, and infrastructure projects alike.

What is Regen?

Regen GGBS (ground granulated blast-furnace slag) is a readily available, reliable 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 650kg, 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.

Applications

Regen is ideal for use in projects where sustainability and durability are essential requirements. Example applications include:

  • Soil stabilisation
  • Mortar
  • Precast concrete
  • Paving and street furniture
  • Specialist projects

Benefits

Regen is a highly sustainable cement substitute. From its low emissions production process to its use in long-life structures, concrete made using Regen provides many sustainability benefits.

  • Low embodied CO2
  • Produces low CO2 concrete
  • No mineral extraction
  • Reduced landfill
  • Meets your criteria for sustainable construction

Durable

  • Produces more durable concrete
  • Concrete made with Regen will last longer in aggressive environments

Attractive

  • Lighter-coloured concrete – near-white
  • Aesthetically pleasing
  • Safer in dark areas

Availability

  • Available nationwide

Support

  • Full package of technical support available

Cost-effective

  • Using Regen is a cost-effective method of making more sustainable and durable concrete

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.
