Researchers in the US have designed an electrochemical route to electrify and decarbonise cement production. The process, which generates calcium carbonate without relying on limestone decomposition, ...

Calcined clay has emerged as a promising supplementary cementitious material (SCM) that can significantly mitigate the carbon footprint of cement production. This article explores the potential of ...

New technologies spurred by federal support show a cleaner path forward for the highly emissive cement and concrete industry. Despite cement’s overwhelming presence, the world has been relatively slow ...

For every 1,000 kilograms of cement the world produces, 600 kilograms of carbon dioxide are dumped into the atmosphere. If that doesn’t sound like a lot, consider that last year the world made about 4 ...
