摘要
通过ＤＴＡ，ＳＥＭ观察和大量Ｘ射线衍射分析，给出了钙矾石稳定存在和结构脱水变异的温度范围以及变异后的结构特征；得出了以钙矾石为膨胀源的自应力水泥混凝土的稳定使用范围。
By means of DTA, SEM and XRD, the range of temperature for the stability of crystal and the variation of structure due to dehydration of ettringite is studied. And the range of temperature for the stability of the self stressed cement and concrete with ettringite as an expanding agent is suggested.
