    Environmental impact. Limestone Calcined Clay Cement is a low-carbon alternative to the standard Portland cement. LC3 can reduce CO2 emissions related to cement manufacturing of cement by reducing the amount of clinker, replacing it with limestone and calcined clays. Low-grade kaoline clays can be used for the production of LC3 and are abundantly available in many parts of the world.
