Abstract
This study revealed the difference of specific surface and replacement rate of Fly Ash in the production of tobermorite by the hydrothermal reaction.In this study Fly Ash was classified one sanple. So Fly Ash had same chemical and mineral component. After hydrothermal reaction, the production amount of tobermorite was decreased by increasing of the replacement rate and the specific surface of Fly Ash. The peak of tobermorite (002) was shifted to low angle along with dissolution of Al in Fly Ash.
