Portland cement

Application
The Standard Reference Material (SRM) is primarily intended to calibrate or evaluate methods used for analyzing cements and materials with similar matrix.
Features and Benefits
NIST certified mass fraction values for the elements in Portland cement are metrologically traceable to the SI derived unit of mass fraction and expressed as a percentage.
Reference mass fraction values and information mass fraction values for various constituents present in cement are provided.
Maintenance and expiration of SRM certification, instructions for handling, storage, and use are provided on NIST certificate.
General description
A unit of SRM 1880b contains five sealed vials, each containing ~ 5 grams of Portland cement finely ground to pass through a 75 µm (No. 200) sieve. For more information, pleases refer to the COA and SDS.
