Mössbauer study of synthetic and extracted brownmillerite from sulfate resisting Portland cements'
Abstract This study investigates the quantitative distribution of iron between the two crystallographic sites of brownmillerite isolated in a previous study from four sulfate resisting (SR) Portland cement clinkers. 57 Fe Mössbauer spectroscopy was combined with powder x‐ray diffraction (XRD) in order to determine the balance between Fe 3+ and Al 3+ ions in the tetrahedral and octahedral sites of the orthorhombic structure. Synthetic samples covering the whole composition range were studied for protocol validation.
