| 摘 要： | 运用化学分析、ＸＲＤ、ＳＥＭ、ＤＴＡ等测试手段，研究了稀土氧化物Ｌａ２Ｏ３对Ａ矿性质及其水化性能的影响。结果表明：Ｌａ２Ｏ３的掺入细化了Ａ矿晶体，并使Ａ矿晶系由三斜向单斜转变。随着Ｌａ２Ｏ３掺量增加，Ａ矿水化速度及其浆体强度（尤其是早期强度）不断降低，凝结时间不断延长

THE PROPERTIES AND HYDRATION CHARACTERISTICS OF ALITE DOPED La 2O 3 |

| Abstract: | The effect of the rare earth oxide La 2O 3 on the characteristics of alite and its hydration properties are studied by using the measuring methods such as chemical analysis, XRD, SEM, DTA etc. The results show that the added La 2O 3 minimizes the crystal alite and leads its crystallographic system to change from triclinic system to monoclinic system. With the increase of the added amount of La 2O 3, the hydration velocity and the paste strength (especially for the early strength) of alite are decended, and the setting time of paste is length ened. |
