Portland cement

Application
The SRM1884B is a Type III portland cement intended to evaluate and calibrate the methods to analyze the cements and materials of similar matrix.
Features and Benefits
Accompanied with certificate documenting NIST- certified mass fraction values, and coverage factor for the constituents in portland cement.
The reference and information values of constituents are reported as mass fraction.
The certified value is metrologically traceable to the SI unit of mass fraction, expressed as a percentage.
The NIST certificate is provided with expiration certificate, use, storage, handling, and maintenance instructions.
General description
One unit of SRM 1887b contains five vials, each sealed with ~ 4 g of portland cement which is ground to pass through a sieve of 75 µm (No. 200).
