A new type of low-carbon cement that is based on a blend of limestone and calcined clay is gaining acceptance in developing countries and is expected to be commercially produced next year in South America. It is tolerant of impurities in its components, competitive in performance and economics with ordinary Portland cement and can reduce carbon dioxide emissions by up to 30%.

Limestone Calcined Clay Cement (LC3) has been developed by an international team of researchers coordinated by EPFL (Swiss Federal Institute of Technology at Lausanne), a consortium.
