Capital Concrete trials low-carbon cement

Capital Concrete has supplied an innovative low-carbon concrete for the foundation slabs of a new STOREX storage facility in Sunbury. The concrete uses Re-ment, a sustainable cement technology developed by Swedish producer Cemvision.

Re-ment replaces traditional limestone-based cement with two binders made from industrial waste products, reducing the carbon footprint of the cement production process. Tests showed that using Re-ment reduced CO2 emissions by up to 75% compared to traditional Portland cement, helping the project meet its sustainability targets.

Jack Sindhu, technical director at Capital Concrete, said the product performed well during the trial: "The product proved easy to batch, working seamlessly with traditional aggregates and admixtures. In addition, we worked with the Cemvision team to adapt the formula, allowing for the concrete to have a longer open life to accommodate the travel time from the plant to the construction site. Being involved in this project and working with the team at Cemvision has been a pleasure.”

Capital Concrete worked closely with Cemvision throughout the project, providing a silo for trials and carrying out tests and evaluations to ensure the concrete met performance standards.

Luke Smith, managing director at Capital Concrete, said the company is committed to sustainable construction: “At Capital Concrete we’re committed to providing sustainable solutions for our customers that have a reduced impact on the environment while maintaining performance. We are proud to have been involved in an innovative project such as this — well done to the team for their hard work in producing, testing, and delivering the material.”

Re-ment’s successful use in this project highlights the potential for reducing emissions in the concrete sector through alternative cement technology.
