Available in PDF, EPUB and Kindle. Book excerpt: A new Standard Reference Material (SRM) for portland cement clinker has been produced for the Office of Standard Reference Materials at the National Institute of Standards and Technology (NIST). The SRM clinkers are intended for use in developing and testing quantitative methods of phase analysis for portland cement and cement clinker. The new SRM is one of three clinkers available from NIST representing the range of textures and compositions of North American clinker production. As the original SRM stock for SRM2687 has been depleted, new material was obtained that retained the fine-grained texture of that 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) analyses. The XRD data were subdivided to provide two separate sample sets and were processed by two different Rietveld refinement codes. These codes differed slightly in the determination of the silicate phases, which have very similar powder diffraction patterns and can be difficult to decompose. Therefore, the input data set for determination of the consensus means, uncertainties and informational values is composed of two distinct XRD data sets and one SEM/image analysis data set. The XRD data are close to that determined by microscopy, but some distinct differences are seen. The disagreements may reflect the difficulty in resolving the fine-sized aluminate and ferrite interstitial phases using the microscope and challenges in decomposing highly overlapped powder diffraction data. The XRD data do display greater precision than replicate measurements by microscopy, likely the result of the specimen homogenization resulting from grinding the clinker to a powder. The certified reference values are consensus values, calcuated by combining the results from both measurement techniques using the DerSimonian-Laird method with the standard un

Download or read book Standard Reference Materials written by John K. Taylor and published by DIANE Publishing. This book was released on 1997-07 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook was prepared with the objective of improving the understanding of the basis for the use of Standard Reference Materials (SRMs). While written from the viewpoint of a chemist, the basic concepts described are believed to be applicable to most areas of metrology. The handbook is arranged by section in a logical progression, starting with the basic concepts of precision & accuracy, followed by discussions of the calibration & quality assurance of the measurement process, the use of SRMs to evaluate various kinds of measurements, & the reporting of data with evaluated limits of uncertainty. Charts & tables.
