摘要：

T1, T3 and M3 polymorphs of the tricalcium silicate (C3S) were prepared at 1500°C via doping of MgO at 0, 0.6% and 1.5% (mass fraction). The diffraction data of the samples were obtained by X-ray diffractometer with different resolutions. The results show that the fingerprint patterns of the X-ray powder diffraction for the C3S polymorphs are identical, which can be used to investigate the polymorphism of C3S. The diffraction peaks for C3S polymorphs are broadened and vague, and some peaks are overlapped under the measurement condition of a lower resolution (full width at half maximum (FWHM)≥0.129°) and Ka2 radiation. When the data are collected at a higher resolution (FWHM≤0.072°) without Ka2, the patterns are identical to distinguish the polymorphism of C3S.
