Abstract:X-ray Diffraction (XRD) technique was normally used to determine the cement hydration products such as Ettringite (Aft), Monosulfate (AFm) and Portlandite (Ca(OH)2 ) . The hydrated sample has to be prepared in dry powder and the cement hydration reaction has to be stopped at specific time. It was not practical to study the hydration at very early age . To overcome this limitation, , the in situ Wide Angle X-ray Scattering technique (WAXS) was used to investigate cement hydration. Because of the high intensity of synchrotron x-rays, the measurement time was shortened reduced. This enables the study of cement hydration at very early age by the WAXS technique which gave valuable information for the understanding of cement properties such as workability and early compressive strength.
