| 摘 要： | 采用差热分析、Ｘ射线衍射曲线、扫描电镜对掺ＵＥＡ膨胀剂水泥２８ｄ及１０ａ龄期的水化产物进行比较研究，并且采用高压水银侧孔仪对２８ｄ及１０ａ龄期的ＵＥＡ砂浆的孔结构进行分析。结果表明随着龄期的增长，掺ＵＥＡ膨胀剂的水泥石结构趋于密实，通过对掺ＵＥＡ的水泥砂浆和混凝土长期物理力学性能和膨胀性能的研究，表明掺ＵＥＡ混缔造长剂的砂浆和混凝土是稳定的。本工作对补偿收缩混凝土应用具有指导意义。

| Abstract: | The hydration products of cement with the addition of UEA expanding admixture, the expansive characteristics as well as the physical_mechanical properties of cement mortar and concrete both with UEA were investigated. The long_term stability of the system is discussed in the paper. The research results have a guiding effect on the application of shrinkage_compensation concrete. |
