MOERDIJK, Netherlands – 8 July 2026 – Ecocem has successfully demonstrated its ACT low-carbon cement technology in industrial-scale precast concrete production for the first time, reducing the concrete’s carbon footprint by 67.5% while meeting the demanding performance requirements of one of the construction industry’s most technically challenging manufacturing environments.
The trial, carried out in partnership with Belgian precast concrete specialist C-concrete at its production facility near Antwerp, saw two full-scale precast elements—a 10 × 3 metre fire-resistant wall and an 8 × 3 metre insulated sandwich wall—manufactured using ACT under normal factory production conditions.
Precast concrete is one of the construction sector’s most technically demanding applications, requiring rapid strength development, consistent quality and efficient demoulding to maintain production schedules. Successfully demonstrating ACT under these conditions marks another important milestone in the commercial deployment of low-carbon cement technologies.
A Life Cycle Assessment (LCA) undertaken by C-concrete found that the ACT concrete reduced the carbon footprint of both elements by 67.5% compared with conventional cement.
The successful trial demonstrated that ACT integrated seamlessly into C-concrete’s existing precast production processes, meeting the demanding performance requirements of industrial precast manufacturing without changes to establishedmanufacturing practices.
Jaouad Nadah, Head of ACT Implementation at Ecocem, said: “We’re delighted to see ACT perform at full factory scale exactly as it did in the laboratory—with no surprises and no production issues.”
Nikolas Schack, Quality Manager and Concrete Technologist at C-concrete, added: “The feedback from our production team has been extremely positive. ACT performs like conventional cement while delivering a significantly lower carbon footprint.”
Simon Maillet, Sustainability Manager at Cordeel Group, said: “Collaborations like this are essential to accelerating more sustainable construction. Demonstrating new technologies under real production conditions gives the industry confidence that lower-carbon solutions are ready for wider adoption.”
Developed over more than a decade of research and innovation, ACT is Ecocem’s breakthrough low-carbon cement technology. By replacing up to 70% of clinker—the most carbon-intensive component of cement—with a combination of low-carbon supplementary cementitious materials and limestone filler, ACT can reduce cement emissions by up to 70%.
Designed as a drop-in technology, ACT delivers the strength, durability, workability and cost competitiveness of conventional cement without requiring changes to existing cement manufacturing, concrete production or construction practices.
The successful precast trial adds to a growing portfolio of commercial ACT applications across Europe, including the world’s first residential development constructed entirely using ACT concrete in Chessy, France, and the technology’s first permanent deployment on UK infrastructure. Together, these projects demonstrate that deep reductions in cement emissions can now be achieved across multiple construction applications using commercially available technology.
