Abstract An extensive dataset suitable for kinetic calculations was collected for the hydration of monoclinic alite at water to solid ratios of 10 and 0.5. The measurement methods used to investigate the hydration behavior are XRD, TGA, solid state NMR, BET, SEM and ICP-OES. A comparison of the two water to solid ratios shows only minor effects of the w/s-ratio on the reaction kinetics. Reaction rates for the two kinetic steps alite dissolution and C-S-H precipitation are calculated from this dataset and compared to the measured reaction rates. Computed reaction rates from C-S-H precipitation show a good match with the measured reaction rates, indicating that the computation incorporates all relevant factors related to C-S-H precipitation kinetics during hydration.

水合过程中的 Alite 溶解和 CSH 沉淀速率

摘要 收集了适用于动力学计算的广泛数据集，用于水固比为 10 和 0.5 的单斜晶石水合。用于研究水合行为的测量方法是 XRD、TGA、固态 NMR、BET、SEM 和 ICP-OES。两种水固比的比较表明 w/s 比对反应动力学的影响很小。两个动力学步骤 alite 溶解和 CSH 沉淀的反应速率是从这个数据集计算出来的，并与测量的反应速率进行比较。由 CSH 沉淀计算的反应速率显示出与测量反应速率的良好匹配，表明该计算结合了与水合过程中 CSH 沉淀动力学相关的所有相关因素。
