SRM 2687a Portland Cement Clinker Development Data Analyses, and Certification
Paul E. Stutzman
The Standard Reference Material (SRM) clinkers are intended for use in developing and testing quantitative methods of phase analysis for portland cement and cement clinker. The three NIST clinkers exhibit the range of textures and compositions of North American clinker production. As the original SRM stock is depleted, new material was obtained that retained the fine-grained texture of the original SRM. Certification of the phase composition of the clinker is based upon consensus means and uncertainties of two independent analytical methods: scanning electron microscopy with image analysis and X-ray powder diffraction (XRD). The certified reference values will be calculated by combining the results from all of the measurement methods with the standard uncertainties. Informational values representing best estimates based upon a single analytical method are provided for some phases assesed by a single method and for the bulk oxides.
