The individual subsystems of the basic five component oxide system CaO-SiO2-AI203-Fe203-SO 3 are analysed for their subsolidus phase relationship. The study is confined to the portion of the system in which C2S, the key mineralogical component of belite clinker is present. As a result eighteen equil

✦ Synopsis
The mineralogical (phase) composition of sulphoaluminate belite cement clinkers was calculated using phase compatibility data of the relevant portion of the five component oxide system CaO-SiO2-A1203-Fe203-SO 3 and was plotted in the plane of three component raw mix. In result a phase fields map (PFM) was obtained showing equilibrium changes in phase composition of clinkers on changes in the raw mixture composition.
