Limestone calcined clay cement - Decarbonizing cement industry Innovation Insights - CLIMAX
Limestone is a widely used raw material in the manufacture of cement. However, considering the CO2 emissions from the process and the need for high temperature conditions, calcined clay is being suggested.
Now a new type of cement is being explored which is a combination of limestone and calcined clay. Called LC3, it is made using limestone and low-grade clays which are available in abundant quantities. LC3 can reduce CO2 emissions by up to 40%, is cost effective and does not require capital intensive modifications to existing cement plants.
