Cemfree was created in 2011 to tackle construction’s biggest climate challenges. We’ve partnered with academia and industry to develop and deploy advanced ultra-low carbon concrete technologies.
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.
Concrete is humanity’s second most used product, second only to water. At that scale, the industry produces 8% of the world’s CO2 pollution, a terrifying 4 billion tonnes every single year. Getting that number down is a big challenge, but the right tools for the job are here today. We’re helping industry leaders use their existing plant infrastructure, production processes, and placement techniques to make greener concrete. Years of expert development have produced one of the best carbon savings on today’s market.
Our experts partner with your experts to build a process around your project’s demands. Rely on us from planning to development, all the way to on-site pour support.
Cemfree products are constantly being developed, refined, and expanded to help more building projects cut carbon at scale. Talk to us about crafting a solution around your specific requirements.
