XRD analysis of hydrated cements and cementitious systems

Application of the Rietveld method for determination of different amorphous phases in blended cements

Rietveld analysis of a hydrated mixture of Portland cement, slag, fly ash and limestone was performed in order to determine the relative quantities of the crystalline and amorphous phases in a single unhydrated sample and five variously hydrated samples. The results were analyzed so as to distinguish and to quantify the different amorphous phases.

In this application note we will reveal a methodology that allows the quantification of the individual amorphous (or poorly crystalline) contributions. Using this strategy we determine the reaction kinetics of a blended cement containing both fly ash and slag.
