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 2 8d及 1 0a龄期的水化产物进行比较研究 ,并且采用高压水银测孔仪对 2 8d及 1 0a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的长期物理力学性能和膨胀性能的研究 ,表明掺UEA混凝土膨胀剂的砂浆和混凝土是稳定的 .本工作对补偿收缩混凝土的应用具有指导意义 .
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.
