SRM2688 Portland Cement Clinker Standard

English name: Portland Cement Clinker

Brand: NIST standard substance from the United States

thatSRM2688 Portland Cement Clinker StandardThe specification is a set of 3 sealed small bottles, each containing about 10 grams of crushed Portland cement clinker. After homogenization treatment, the uniformity inside and between the bottles is good. Its certification value is expressed in terms of quality score, based on the consensus results of NIST's quantitative X-ray powder diffraction (QXRD, combined with Rietveld refinement) and optical microscope point counting analysis. The extended uncertainty is calculated to cover factor 2, and information values such as bulk oxides are provided. The information values do not evaluate uncertainty and are only for reference and are not used to establish metrological traceability [3].

SRM2688 Portland cement clinker standard is widely used in the fields of chemical engineering, building materials testing, etc. It can be used for the development, verification, and laboratory quality control of cement clinker phase analysis methods. Its certification value has fully considered various sources of deviation, providing reliable technical support for improving the accuracy of cement clinker testing and ensuring the quality of related products.
