Description
This Standard Reference Material (SRM®) is intended for use in evaluating methods of phase abundance analysis of major phases in cement clinkers: the percentages of alite (C3S), belite (C2S), aluminate (C3A), ferrite (C4AF), and arcanite (K2SO4). A unit of NIST-2687 consists of three hermetically sealed vials, each containing approximately 10 g of crushed portland cement clinker. The materials selected for SRMs 2686a, 2687, and 2688 differ widely in phase abundance, crystal sizes, and distribution of crystals. /// Sample value(s) - please ask for current certificate.

NIST provides over 1300 Standard Reference Materials® as well as articles and practice guides describing the development, analysis and use of SRMs.
NIST Standard Reference Materials are used by analytical laboratories in industry, academia and government in order to facilitate commerce and trade and to advance research and development. The SRMs are produced by the engineering laboratory, the material measurement laboratory, and the physical measurement laboratory at NIST. They are available for chemical composition, physical properties, and engineering materials.
