Cemfree can transform your construction projects, reduce carbon emissions and enhance durability.

The solution is Cemfree

Cemfree products cut carbon by up to 85% compared to traditional Portland cement. Along with industry-leading consultancy and on-site support, our products let project teams and contractors realise their climate ambitions today.

Driven by technology at every step

Cemfree is a patented, award-winning alkali-activated cementitious material (AACM). Years of development have produced an industry-leading, acid-resistant solution that’s whiter than white cement. Rigorous PAS8820-standard testing proves its strength can go toe-to-toe with traditional concrete.

Research and development leading the way

Our 6-strong dedicated R&D team are always pushing the boundaries of sustainable construction by developing and refining new products. Whether working from our in-house labs or attending on-site trials, we add value across the whole project lifecycle.

Along with our ongoing collaborations with academia, we also advise the construction industry at the highest levels. Cemfree experts sit on professional committees and bodies like:

  • Innovate UK
  • The Association of Alkali Activated Cementitious Materials (A3CM)
  • BSI Mortar Standard Committee
  • MPA Mortar Committee
  • Low Carbon Concrete Group (LCCG)
  • LOCOWAG
