Clinker: combinability of mixes - Understanding Cement
The bulk of the clinker remains as a solid. 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 ...

This calculation is based on the hypothesis that the main oxides in clinker are four (s,a,f,c) and that they combine in four phases (c3s,c2s,c3a,c4af). (the intitial assumption) If you have a certain mix of the four main oxides (s,a,f,c), you can calculate how much of the four clinker phases you can get from that: (c3s,c2s,c3a,c4af).

Fractional crystallization of salt solutions : Phasediagram
Fractional crystallization is a method for separating salts from solutions. The method is based on the fact that the solubility of each salt has a unique temperature dependency. In industry, this method is used to separate multi-component salt solutions into pure salts and water. Such salt solutions can be the effluents from solution mining, by ...
