Abstract

The compatibility of phases within the CaO−SiO2−
Al2O3−SO3−Fe2O3 system is revisited. The influence of the SO2 partial
pressure on the formation of phases and the stability of phase
assemblages is addressed by means of new experimental methods
(performed under controlled atmospheres) and thermodynamic
calculations. Existing data from the literature are compiled and compared
with the results obtained from this work. The results obtained are linked
to real clinker formulations, and practical implications are discussed.
