Study on the Change in Microstructure of Fly Ash Concrete Depending on Ages and Degree of Hydration Using XRD and SEM

Abstract:

This research analyzes the microstructure of hardened blended cement pastes. Fly ash was used to replace Portland cement type I paste. Test results indicated that hardened blended cement paste were significantly affected by duration after mixing. The X-ray diffraction (XRD) and the scanning electron microscope (SEM) showed changes of microstructure by duration.
