Why LC3? LC3 Limestone Calcined Clay Cement

Grinding limestone takes less energy than heating it; Calcination of clay takes place at 800°C and uses roughly 55% of the energy needed for clinkerisation at 1450°C. Existing equipment can be used. LC3 can be produced with existing manufacturing equipment, leading to only marginally increased investments for calcining equipment.
