Guide for X-Ray Powder Diffraction Analysis of Portland Cement and Clinker

摘要

Accurate, rapid methods for determining phase abundance are necessary to aid in classification of cements and for correlation of performance characteristics with composition. X-ray powder diffraction is a direct method for qualitative and quantitative phase abundance analysis of fine-grained materials. While the application of powder diffraction in the cement industry is well established for qualitative analysis, its use in the determination of phase abundance is not as common. This guide examines methods for compositional analysis of portland-cement clinker and cement by X-ray powder diffraction through examples of diffraction pattern profile regions used in phase and polymorph identification, and demonstration of a procedure for calibration and quantitative phase abundance analysis.
