At the highest temperatures reached by the clinker, perhaps only about 25% of the clinker is a liquid and the solid phases are then mainly alite, belite and free lime. 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.
