Discover LC3?
LC3 stands for Limestone Calcined Clay Cement. It is a combination of clinker, calcined clay, limestone and gypsum. The cement blend uses 50% clinker, 15% non-cement grade (high silica or high MgO content) limestone, 30% calcined low grade china clay (non-ceramic grade) from mines and 5% gypsum.
