Solidification of the clinker liquid indications from pure systems

1 Solidification of the clinker liquid indications from pure systems 

In principle, the clinker liquid can behave in any of three ways during cooling, with intermediate possibilities. In the first, equilibrium between the liquid and the pre-existing solid phases (alite and belite) is continuously maintained. This implies the possibility of material transfer between these solids and the liquid in either direction for as long as any liquid remains. We shall call this situation equilibrium crystallization . In the second, the liquid does not crystallize but forms a glass. In the third, the liquid crystallizes independently, i.e. without interacting with the solid phases already present. Intermediate modes include, for example, equilibrium crystallization down to a certain temperature and independent crystallization below it. 

Lea and Parker (L5) found that, in the pure Ca0-Al203-Fe203-Si02
