    Abstract

    The X-ray diffraction pattern of KC8A3 has been determined in detail. Comparison of the KC8A3 data with new and previous X-ray diffraction data on NC8A3 and C3A shows it to be a distinctly different phase bearing close structural similarities to the other aluminates in portland cement clinker. The progression from cubic C3A to tetragonal KC8A3 to orthorhombic NC8A3 with only minor shifts in cell parameters suggests the possibility of solid solution between respective adjacent pairs in production clinkers.
