Solid state compatibilities in CaO-CaO.Al2O3-CaSO4-CaF2 system

摘要

The determination of the phases assemblages in equilibrium in the CaO-CaO.Al2O3-CaSO4CaF2 system at 1100 degrees C has been performed. Four assemblages are found and one more is deduced. 3CA.CaSO4 appears in all compatibility tetrahedra in solid state or in melt presence. It is compatible with C(3)A, C(12)A(7)ss, CA, C(11)A(7).CaF2 and the aluminate formed depends on Al2O3 and CaF2 proportion, (cement chemistry abbreviations: C = CaO, A = Al2O3).
