Microscopy and Microanalysis. ISSN 1431-9276. Vol. 19, Supp. 4 (2013), pp. 97-981431-92761435-8115http://hdl.handle.net/10400.21/11772In the present study waste FCC catalyst has been incorporated in cement paste mortars with a 15:85 weight ratio. The microstructural evolution of the blended materials has been investigated by X-ray diffraction and scanning electron microscopy coupled with X-ray energy dispersive spectroscopy after curing times of 2, 7 and 28 days. Namely, the evolutions of the catalyst crystal structure and of the calcium content in the dispersed catalyst particles have been evaluated.engCementX-rayMicroscopyCatalyst crystaljournal article10.1017/S1431927613001104
