摘要：
The surface microstructure of tricalcium silicate (C3S) was observed by transmission electron microscopy (TEM). The tricalcium silicate specimen was dispersed in ethanol or isopropanol. It was then placed on a copper mesh with a collodion film that had an amorphous layer on the surface of each grain. The amorphous layer was caused by the hydration reaction of C3S with water in the dispersants. The irradiation by an electron beam caused the layer to change into CaO crystallites with a concurrent formation of silica-rich domains.
