A utility company has used a Portland cement-free form of concrete in a construction project in a bid to slash carbon emissions.
Anglian Water used Cemfree in the base for a kiosk housing technical monitoring equipment at a water treatment works in Norfolk.
The material, produced by Cambridgeshire-based David Ball Group, uses ground blast furnace slag rather than Portland cement and is designed to reduce embodied carbon in structures.
Anglian Water has pledged to deliver a 70% reduction in embodied carbon by 2030.
Fionn Boyle, innovation technologist at the water firm, said: “We’re starting small, but this new material has big potential.
“We’re always looking for new ways to reduce our carbon emissions and, as a company that relies on our infrastructure and physical assets, it made sense to concentrate on the construction materials we use. Concrete is a big contributor to greenhouse gas emissions, but it is a vital material on all our treatment sites.
“We will be vigorously testing [Cemfree] with involvement and technical expertise from our design and construction partners to ensure it meets our standards, and in the future we will be looking at ways we can use it to replace traditional concrete.
“We’re at the start of the testing phase for this new innovation, and if it does prove to be valuable to us we hope others in the industry will be able to learn from our experiences. We’re committed to investing in innovation, not just to benefit our business but to also to benefit our environment.”
