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. ⁵⁷Fe Mössbauer spectroscopy was combined with powder x-ray diffraction (XRD) in order to determine the balance between Fe³⁺ and Al³⁺ ions in the tetrahedral and octahedral sites of the orthorhombic structure. Synthetic samples covering the whole composition range were studied for protocol validation.
