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
