Abstract:This project established protocols and specifications for the direct determination of cement composition by Quantitative X-ray Diffraction (QXRD). The main objectives of this research were: 1) developing protocols for routinely performing QXRD testing, 2) testing the effectiveness of the protocols using commercial cement samples, and 3) documenting the potential qualitative and economic benefits of utilizing QXRD. Researchers developed a state of the art QXRD methodology through regular collaboration and knowledge transfer with industrial experts. In addition to the important findings, further recommendations to improve the current phase quantification were proposed to address some of the gaps in existing research and testing. Researchers predicted the financial implications using life-cycle cost analysis procedures if industrial quality control adopts these protocols. The conclusions, both important and supplementary, were recorded with recommendations for future implementation projects.
