First official users on the Powder Diffraction station of BL04
The group from Malaga University came on October 2nd and aimed in studying the behavior of a new type of eco-cement under in-situ conditions (hydration, temperature,…).
Typical results are shown in following Figures. Data were collected at 20 keV using the ´high throughput´ MYTHEN detector.
The Figure 1 shows the hydration evolution of an eco-cement hydrated over the 24 first hours.

The Figure 2 displays observed and calculated patterns (fitted by Rietveld method) at selected times of hydration. Main peaks due to a given phase have been labeled. Calculations allowed to determine weight percentage of each constituting phase (e.g. ettringite) at each time of the hydration process. Complete measurements of 5 samples were performed.
