This work presents a novel way to use X-ray diffraction (XRD) to quantify the plate-like calcium-aluminate-hydrate phases C₂AH_x (2CaO·Al₂O₃·xH₂O), for which three different basal spacings are detected during early hydration at ambient temperatures. By combining Rietveld refinement and the G-factor method, C₂AH_7.5 was calibrated using a variety of syntheses and preparations for XRD. Since cell volume and X-ray density (that are necessary for the G-factor method) of C₂AH_7.5 are not known, an approach similar to [1], [2] was used for the generation of a hkl-phase model: A “F-factor” – a factor that replaces the product of these two unknowns, which was verified by the multitude of syntheses – was successfully determined within this paper. The model was applied for the absolute quantification of C₂AH_x during in-situ XRD of CA (CaO·Al₂O₃) hydration at 40 °C. The results demonstrate the potential of the hkl-phase model in practical use and reveal the accuracy of the determined F-factor.

这项工作提出了一种使用 X 射线衍射 (XRD) 来量化片状铝酸钙水合物相 C ₂ AH _x (2CaO·Al ₂ O ₃ ·xH ₂ O) 的新方法，其中三种不同的基底间距在环境温度下的早期水合过程中检测到。通过结合 Rietveld 精修和 G 因子方法，C ₂ AH _7.5使用各种 XRD 合成和制备方法进行校准。_{由于 C 2} AH _7.5的细胞体积和 X 射线密度（G 因子方法所必需的）未知，类似于 [1]、[2] 的方法被用于生成 hkl 相模型：“F 因子”——替代这两个未知数乘积的因子，已由多种合成——在本文中成功确定。该模型应用于CA (CaO·Al ₂ O ₃ ) 在40℃水合的原位XRD 过程中C ₂ AH _{x的绝对量化。}结果证明了hkl相模型在实际应用中的潜力，并揭示了确定的F因子的准确性。
