About LC3

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.

Benefits of LC3

Due to the lower clinker content, the LC3 technology has several advantages over Ordinary Portland Cement (OPC) and fly ash based Portland Pozzolana Cement (PPC). Notable amongst them are:

  • Lower CO2 emissions
  • Lower production energy than OPC
  • Lower production cost than OPC and PPC in many scenarios
  • Utilization of non-commercial grade raw materials
  • Similar strengths compared to OPC and PPC
  • Improved durability properties
  • Can be integrated within existing cement production system
  • No high capital investment
  • Almost double the production using existing plant and machinery


I have been leading the research & development of the limestone calcined clay cement (LC3) (a new type of cement based on a blend of limestone and calcined clay) through the LC3 project supported by SDC Switzerland.
I confidently state that LC3TRC at TARA India can address all requirements to implement the LC3 technology by cement/prefab/RMC industry worldwide.

Professor, EPFL

I have been involved with the LC3 project in India for the last five years as a Consultant to EPFL. It is a matter of great satisfaction that the development of technology has come to a stage of industrial adoption.
The setting up of TRC is a very logical step for technology proliferation. I would consider it a privilege if the TRC clients find it advantageous to make use of my advisory services in the technology transfer process.
