高水速凝材料硬化体微观特征分析

Analysis of Microscopic Properties of Hardened Mass of Accelerating Materials with High Water Content

通过对高水速凝材料硬化体物相结构和微观形貌分析，揭示了其主要物相构成。由于其组成主要是细长纤维状的钙矾石晶体，且孔隙中填充有大量自由水，从而使硬化体总含水质量比达７０％以上，成为高水速凝材料的最主要特点，且不易粉化，适宜于井下充填。

he composition of the main phases of the hardened mass of accelerating materials with high water content was revealed through the analyses of its phase structure and microscopic topography.As it is mainly composed of ettringitse crystalls in slim fabric shape and lots of free water exist in the voids,so that the mass of the total water content of the hardened mass comes up to 70% and becomes the most important property of the accelerating materials with high water content.This hardened mass is not easy to powder and suited for underground filling.
