An AFm phase is an "alumina, ferric oxide, monosulfate" phase, or aluminate ferrite monosulfate, or Al2O3, Fe2O3 mono, in cement chemist notation. AFm phases are important in the hydration of hydraulic cements. They are crystalline hydrates with general, simplified formula 3CaO·(Al,Fe)2O3·CaSO4·nH2O where n may be comprised between 13 and 19 water molecules. They form inter alia when tricalcium aluminate (C3A: 3CaO·Al2O3) reacts with dissolved calcium sulfate (CaSO4).
