Abstract

Recently, the amount of the exhaust of fly ash increases by increasing thermal power plant. Using it as a concrete mixture material is an effective method for decreasing waste. However, the influence on the hydration of the cement and reaction rate of fly ash is not examined in detail. Then, the cement paste that mixed fly ash examined it by Backscattered Electron image and element image measured by Energy Dispersive X-ray analysis in this research. As a result, reaction rate of fly ash and distribution of fly ash and cement in the fly ash-cement pastes were clarified. And the amount of composition in fly ash cement paste was cleared.
