In the CEMHYD3D model, this reaction becomes active only when the initial calcium sulfate is depleted and the previously formed ettringite begins to convert to the Afm phase by reaction with more of the cement clinker aluminate phases. This is in general agreement with experimental observations [6, 7].

During the hydration of cement, tricalcium aluminate (C3A) reacts with gypsum and forms ettringite (AFt). Once all gypsum is consumed, ettringite can further react with remaining C3A and form monosulfate (AFm) at 1–2 days. Normally, at early ages, ettringite all transfers to AFm phase.

tallographic data are available for the boron-containing AFt phase. AFm phases, which can be formed in significant amounts by hy-drating calcium aluminate cement [26] or a calcium sulfoaluminate cement with a low calcium sulphate content [27], are also interesting candidates to insolubilize borate ions.

Thus in Portland cement, the anions in AFm are hydroxide, sulfate and carbonate while in blended cement, e.g., slag cement, the characteristic anion is an aluminosilicate species. In service, chloride often displaces other anions. The content of AFm phase in hydrated pastes is variable but in many slag-blended cements it may exceed 20%.

The XRD spectra showed no variation in the ettringite content between the C–F–L and C–F samples. However, AFm ss phase was noted in C–F–sL, in addition to the ettringite, at 7 days. This additional AFm ss resulted in an increase in the bound water in H PG1.

According to a literature review the constitution of the AFm phase in Portland cement is very sensitive with respect to its chemical environment. Except for limited replacement of sulfate by hydroxide, AFm phases do not form solid solutions and, from the mineralogical standpoint, behave as separate phases.
