Requirement of White Cement Raw Material. The mineral composition of white cement clinker is basically the same as that of ordinary portland cement (OPC) clinker, mainly C 3 S and C 2 S. The difference is that there is little iron phase mineral C 4 AF in white cement clinker, which is because Fe 2 O 3 has a great impact on the whiteness of cement.

RAW MATERIALS FOR CEMENT MANUFACTURING
Sulphur appears as sulphides (from pyrites). It forms SO 2 in the kiln and with alkalis and oxygen, it forms alkali sulphates which vaporize in the burning zone of the kiln and condense on the raw meal in the colder zone. Though some amount of alkali sulphate in the clinker is of advantage for early strength, high sulphur content can result in increased SO 2 emission, choking of …
