clinker limestone and gypsum ratio in cement

Clinker: compositional parameters -

The LSF calculation can also be applied to Portland cement containing clinker and gypsum if (0.7 x SO 3) is subtracted from the CaO content. NB: This calculation (0.7 x SO 3 ) is based on the ratio of the molar masses of calcum oxide and sulfur trioxide, ie: 56/80 = 7/10.

Cement Clinker - an overview ScienceDirect Topics

The appropriate amount of gypsum depends on the content of C 3 A in the cement and that of SO 3 in gypsum, and it also related to the fineness of cement and the content of SO 3 in clinker. The amount of gypsum should account for 3% ~ 5% of the cement’s mass.

CLINKER GRINDING IN CEMENT PRODUCTION

Clinker (in cement industry) is transitional product in cement production. Upon heating mixture obtained from limestone (about 75%) and clay (about 25%) partial melting occurs and clinker granules are formed. Clinker and gypsum (about 5 %) are mixed and finely milled to obtain cement. Gypsum control the setting properties of the cement.
