X-ray powder diffraction allows direct measurement of the phase content in cement, however, quantification of component phases require rigorous post-acquisition analysis. In this work, an as-received cement was analyzed using a combination of Cu Kα X-ray diffraction, Rietveld refinement and X-ray fluorescence to quantify the initial cement composition. Diffraction and fluorescence were shown to be complimentary techniques for analyzing cement clinker. The cement was then blended with varying amounts of crystalline silica and analyzed using the Rietveld method. Results indicate that the blended cement compositions were in line with calculated quantities of individual components of the cement blend, suggesting the Rietveld method can be used to quantify all crystalline components in a cement blend simultaneously.
