en.Wedoany.com Reported - Ecocem's ACT low-carbon cement technology has reached a key commercialization milestone, with the world's first full-scale residential project built entirely with ACT concrete now completed. Located in Chessy, near Paris, the project named Parker & Baker comprises 147 apartments and 4 houses, utilizing approximately 9,000 cubic meters of concrete made with ACT cement, supplied from a dedicated on-site mobile batching plant.

After over 10 years of research and innovation, Ecocem's ACT cement is a commercially viable low-carbon technology that can reduce cement-related CO2 emissions by up to 70%. The technology achieves deep emission reductions by replacing up to 70% of clinker—the most carbon-intensive component in cement—with abundant low-carbon supplementary cementitious materials and limestone fillers, while maintaining strength, durability, workability, and cost-effectiveness to meet widespread adoption needs. The cement industry accounts for approximately 8% of global CO2 emissions, making scalable low-carbon cement technologies crucial for decarbonizing the construction sector.
The design feature of ACT technology lies in its "plug-and-play" nature, requiring no changes to existing manufacturing processes, batching operations, or construction methods, enabling the construction industry to immediately reduce emissions using existing infrastructure. Prior to the construction of the Parker & Baker project, Ecocem developed four concrete formulations based on ACT cement to meet structural, durability, and operational requirements. Regular quality testing during construction confirmed that ACT cement achieved the required technical performance without compromising concrete quality, construction sequence, or on-site operations. The successful operation of the on-site mobile batching plant using a single cement silo further validated the technology's compatibility with existing construction practices. Compared to the original conventional concrete specifications, the use of ACT cement reduced the project's embodied carbon by approximately 55%.
Olivier Guise, Executive Director of Strategy, Technology, and Development at Ecocem, stated: "With this world first, Ecocem has proven the effectiveness of ACT technology. Concrete produced using ACT demonstrates excellent technical and environmental performance, without requiring changes to how construction sites operate. Large-scale deployment of ACT is now a tangible reality. Ecocem thanks Legendre for exploring new methods and supporting the construction industry's innovation ambitions. Large-scale decarbonization of the construction industry is now more achievable than ever." Vincent Legendre, President of Legendre, commented: "This project demonstrates how technological innovation can realize its full value when implemented on construction sites through partnerships like that between Legendre and Ecocem. True to our culture of innovation, this project marks the first milestone toward broader deployment, with ACT technology to be incorporated into new projects in the coming months."
