Clinker: combinability of mixes Understanding Cement

The liquid is vital in that it acts a flux, promoting reactions by ion transfer; without the liquid phase, combinability would be poor and it would be very difficult to make cement.

Question: How Do You Calculate Clinker Factor?

The Bogue calculation is used to calculate the approximate proportions of the four main minerals in Portland cement clinker. The standard Bogue calculation refers to cement clinker, rather than cement, but it can be adjusted for use with cement. The iron content of the clinker therefore fixes the ferrite content.
