Portland Cement Clinker

Description

• General description: One unit of SRM 2687a consists of five hermetically sealed vials, with each vial containing approximately 8 g of crushed portland cement clinker.SRM 2687A_certSRM 2687A_SDS
• Application: Portland cement clinker standard reference material (SRM) is intended for evaluating techniques used forphase abundance analysis in cement clinkers, including determining the percentages of alite (C3S), belite (C2S), aluminate (C3A), and ferrite (C4AF).
• Features and Benefits: The certified value of the SRM was determined by calculating the mass fraction values of alite (C3S), belite (C2S), aluminate (C3A), and ferrite(C4AF) by quantitative X-ray powder diffraction (QXRD).Certified values are traceable to the International System of Units (SI) and SI-derived unit of mass fraction.Information values for elements arereported as mass fractions. The NIST certificate is provided with expiration certificate, storage, handling,use and maintenance instructions.
• Other Notes: Certified for the analytes listed below. Alite, Belite, Aluminate, FerriteReference/Informational value is provided for the following analytes.Silicon Dioxide (SiO2), Aluminum Oxide (Al2O3), Ferric Oxide (Fe2O3), Calcium Oxide (CaO), Magnesium Oxide (MgO), Sulfur trioxide (SO3), Sodium Oxide (Na2O), Potassium oxide (K2O), Titanium Dioxide (TiO2), Phosphorus pentoxide (P2O5), Manganese(III) oxide (Mn2O3), Strontium oxide (SrO), Zinc oxide (ZnO), Alite, Belite, Aluminate, FerriteSee certificate for values and more details at nist.gov/SRM.
