Heidelberg Materials UK is carrying out trials using CarbonCure technology in ready-mixed concrete, for the first time in England, at its Greenwich concrete plant.
The process involves injecting pure manufactured CO₂ into fresh concrete to improve hydration. This allows producers to use an average of five per cent less cement within the concrete.
Concrete technical director, Daniel Clayton, says; “The CarbonCure trial is the first of its kind to trial the technology in ready-mix concrete in England and is another example of our commitment to innovation and decarbonising our business, to deliver lower carbon construction materials to our customers.
“We’re continuing to invest in a range of innovative technologies to enable this, including partnering with CarbonCure in this trial where the mineralised CO₂ within the concrete stays permanently locked in, even if the concrete is demolished at some point in the future.”
