This paper mainly focuses on revealing the hydration mechanism of new cementitious material of filling body through its microstructure analysis. According to the SEM samples preparation, analysis of different age of filling body microstructure and XRD diffraction mapping, the results showed that the hydration products were with large amount of ettringite, followed by C-S-H gel, calcium and silica. The main reason of strength increasing was the ettringite morphology and the hydration process. It was obtained that the hydration products of different activators were mainly the influence factor of strength, on basis of analyzing the microstructure of different activator materials. |
