Abstract: The hydrated calcium silicate was synthesized in hydrothermal process with different calcium silicon ratio to analyse its impact on the microstructure and polymerization degree of hydrated calcium silicate as the calcium silicon ratio has higher impact on the constitutes and structure of hydrated calcium silicate.With the increase of calcium silicon ratio, the tobermorite and xonotlite were discovered in the XRD.And with the increase of calcium silicon ratio, the surface microstructure of the synthesized particles became looser as shown in the SEM images.By analyzing the IR analysis results, it can be noticed that the polymerization degree decreased with the increase of calcium silicon ratio.
