XRD Rietveld method for the determination of C3A in the clinker from cement analysis cen:proj:81067

Scope

This document describes the analytical procedures used to determine the content of C3A in the
clinker starting from a chemical analysis on cement. The method can be applied to CEM type I
and IV for the determination of the requirement of C3A, as defined on EN 197 1.
This document describes two methods, traditional wet and XRF analysis (EN 196 2), which can
be considered to be equivalent, in the scope of this CEN/TR 17365, for the determination of
Al2O3, Fe2O3 and SO3.
The same methods are described in EN 196 2, but for the scope of this document, the X­ray
fluorescence (XRF) is the preferred method to be used for the determination of Al2O3, Fe2O3
and SO3.
