微珠与硅灰、粉煤灰水化活性的对比研究

Research on Hydration Reactivity of Microsphere Compared with Silica Fume and Fly Ash

为研究微珠对二元复合胶凝材料体系水化硬化的影响机理,以及与粉煤灰、硅灰的差别,作者运用激光粒度分析(Laser Particle Sizer)、X射线衍射分析(XRD)、扫描电子显微镜(SEM)、热重分析(TGA)、微量热仪(Tam Air)、傅里叶红外光谱分析(FTIR)等多种现代微观测试技术,对微珠的水化活性进行了系统的研究。结果表明,微珠的水化活性介于硅灰和粉煤灰二者之间。

In order to carry out the investigation of the hydration reactivity of microsphere and compare with silica fume and fly ash,several modern testing techniques including Laser Particle Sizer,X-ray Diffraction,Scanning Electron Microscope,Thermogravimetic Analysis,Tam Air and Infrared Spectroscopic Analysis have been adopted in this article.The results showed that the hydration reactivity of microsphere was between silica fume and fly ash.
