Clinkering and early age hydration characterization of Belite-Alite Calcium Sulfoaluminate (BACSA) cements
Londono-Zuluaga, Diana; Álvarez-Pinazo, Gema; Tobón, Jorge Iván; García-Aranda, Miguel Ángel; Santacruz-Cruz, Maria Isabel; [et al.] (2015-10-26)In this work, four BACSA clinkers with different compositions (belite ~ 70-55 wt %, alite ~ 10-15 wt % and ye’elimite ~ 10-15 wt %) were synthesized (at laboratory scale). Lime, gypsum, kaolin and sand were used as raw ... -
In-situ early age hydration of cement-based materials by synchrotron X-ray powder diffraction
García-Maté, Marta; Álvarez-Pinazo, Gema; León-Reina, Laura; Gomez-de-la-Torre, Maria de los Angeles; Santacruz-Cruz, Maria Isabel; [et al.] (2015-07-01)Cement based binders are building materials of worldwide importance. Since these samples are very complex, the knowledge/control of their mineralogical composition are essential to design and predict materials with ... -
In-situ hydration studies of ye’elemite at early ages for understanding eco-cement performances'
Cuesta-Garcia, Ana Maria; Álvarez-Pinazo, Gema; Peral, Inma; García-Aranda, Miguel Ángel; Gomez-de-la-Torre, Maria de los Angeles (2013-09-12) -

Quantitative phase Analisis: A comparative study of Mo and Cu strictly monochromatic radiations
Gomez-de-la-Torre, Maria de los Angeles; León-Reina, Laura; Cuesta-Garcia, Ana Maria; García-Maté, Marta; Álvarez-Pinazo, Gema; [et al.] (2016-06-27)A comparison of the Rietveld quantitative phase analyses (RQPA) obtained using Cu-Kα1, Mo-Kα1, and synchrotron strictly monochromatic radiations is presented. The main aim is to test a simple hypothesis: high energy ... -
The use of mo and cu monochromatic radiations for quantitative phase analysis: study of the accuracy
Gomez-de-la-Torre, Maria de los Angeles; León-Reina, Laura; Cuesta-Garcia, Ana Maria; García-Maté, Marta; Álvarez-Pinazo, Gema; [et al.] (2016-06-27)Cement hydration is a very complex process in which crystalline phases are dissolving in water and after supersaturation hydrated crystalline and amorphous phases precipitate. Great efforts are being made to develop ... -
X-ray diffraction, cements and environment, three worlds in one
Zea-Garcia, Jesus D.; Gomez-de-la-Torre, Maria de los Angeles; Santacruz-Cruz, Maria Isabel; Londono-Zuluaga, Diana; García-Maté, Marta; [et al.] (2017-12-13)This keynote lecture will be focused on the strategies for reducing CO2 emissions in the cement production. Concretely, the production of ecocements with optimised formulations that yield reductions in CO2 emissions of up ... -
X-ray powder diffraction applied to cement related phases: in-situ and high resolution applications
Cuesta-Garcia, Ana Maria; Álvarez-Pinazo, Gema; Gomez-de-la-Torre, Maria de los Angeles; Santacruz-Cruz, Maria Isabel; Peral, Inma; [et al.] (2014-07-03)XRPD is a powerful tool for material characterization in general, and for in-situ studies of chemical processes in particular. The use of an intense X-ray source, .i.e. synchrotron X-rays, coupled with fast X-ray detection ...
