World Cement May 2018 comment World Cement

The Cement Sustainability Initiative (CSI) identifies four “carbon mitigation levers”: in addition to carbon capture and storage/utilisation, these are improving energy efficiency, switching to alternative fuels, and reducing the clinker-to-cement ratio.

LC3 (LC3), a new cement made of 50% clinker, 30% calcined clay, 15% limestone, and 5% gypsum, achieves same performances than CEM I. Replacing CEM I by LC3 could reduce total CO2 emissions from Turkish cement industry by 12.4 Mt (based on 2016 figures).
