Waste clay could reduce concrete’s embodied carbon by a third

Description

Using waste clay and brick in concrete production could reduce the material’s embodied carbon by up to 30%.

The finding is the result of a 2 year study led by the MPA , backed by Tarmac. It shows that UK reclaimed clays and finely ground brick powder can be used as calcined clays in cement and concrete manufacturing to deliver lower emissions compared with the market-leading CEM I cement.
