Bulk oxide determinations from a pair of port-land cements provides
the basis for calculation precision and accuracy values for X-ray
fluorescence (XRF) analysis for both the fused glass bead and the
pressed powder sample preparation. This report is the second in a
series on an Inter-laboratory study on chemical analyses of
hydraulic cements by X-ray fluorescence for the purpose of
estimating precision and qualification criteria. Approximately 45
laboratories provided six replicates analyzed in duplicate for two
separate port-land cements containing ca. 5 % limestone, covering
fifteen analytes, CaO, SiO2, Al2O3, Fe2O3, SO3, MgO, Na2O, K2O,
TiO2, P2O5, Mn2O3, SrO, ZnO, Cr2O3, and Cl, with the laboratories
roughly split between the two different sample preparations.
Chemical data using traditional chemical analyses (the Reference
Methods) from the Cement and Concrete Reference Laboratory (CCRL)
proficiency test program were included for comparison to the XRF
results.
