Mineral added to clinker during grounding in ball mill

Feb 21, 2019 Alite (C 3 S = 3CaO*SiO 2) is a soft material, Mohs hardness is 3.2–3.4, the mineral is very fragile and easily damaged. Belite (C 2 S = 2CaO*SiO 2) is the second major mineral of Portland cement clinker, it characterized by a slow hardening, but provides achieving high strength during long solidification of Portland cement. Mohs hardness is 5-6
