Industrial trials start on zero-carbon cement production

The Cement 2 Zero project aims to demonstrate that concrete can be recycled to create a slag forming addition that could, when cooled rapidly, replace Portland cement.  

The two-year industrial trial will test each stage of the production process, bringing together the Materials Processing Institute, the University of Cambridge and industry partners – Atkins, Balfour Beatty, Celsa, Day Aggregates and Tarmac. Eventually the zero carbon cement – known as Cambridge Electric Cement – will be used in a real UK construction project.  

Philippa Horton of the University of Cambridge, who created the project consortium, said: "If Cambridge Electric Cement lives up to the promise it has shown in early laboratory trials, when combined with other innovative technologies, it could be a pivotal point in the journey to a zero-emissions society."
