对不同煅烧方法所得 C_2S 水化活性的 SEM 研究

A STUDY ON THE HYDRATION ACTIVITY OF C 2S OBTAINED FROM DIFFERENT BURNING PROCESSES BY MEANS OF SEM

用普通煅烧方法和快速升温煅烧方法制备了Ｃ２Ｓ试样，并用扫描电子显微镜（ＳＥＭ）直接观察了它们的水化情况。结果显示用快速升温方法制备的Ｃ２Ｓ具有较高的水化活性。该结论为改善Ｃ２Ｓ的水化活性提供了实事依据。

The samples of C 2S were prepared by ordinary burning method and rapid burning method.Then their hydration performances were observed by means of scanning electron microscope(SEM).The results show that C 2S obtained from rapid burning method has higher hydration activity.This conclusion provides a factual evidence for improving the hydration activity of C 2S.
