LC3 is a new type of cement that is based on a blend of limestone and calcined clay. LC3 can reduce CO2 emissions by up to 30%, is made using limestone and low-grade clays which are available in abundant quantities, is cost effective and does not require capital intensive modifications to existing cement plants.
What makes LC3 a real and viable solution for Low Carbon Cement to be used on a global scale?
LC3 can be produced with existing manufacturing leading to only marginally increased investments for calcining equipment.
Reduced clinker content, reduced fuel consumption for calcination compared to clinker contribute to lowering production costs.
Clinker – Limestone systems and Clinker – Calcined Clay systems are well established. LC3 is not about inventing a new technology but optimizing the synergy between two already known chemical systems.
