• Alite-belite-ye'elimite cements: Effect of dopants on the clinker phase composition and properties 

      Zea-Garcia, Jesus D.; García-Aranda, Miguel Ángel; Gomez-de-la-Torre, Maria de los Angeles; Santacruz-Cruz, Maria Isabel (2018-10-30)
      Clinkers with alite-belite-ye'elimite (ABY) are considered as eco-friendly cements. Clinkering (2 Kg) of two types of ABY clinkers was optimized: standard-ABY, with CaF2 and ZnO as dopants (32.6 wt% alite, 30.4 wt% β-C2S ...
    • In situ hydration imaging study of a ye'elimite paste by ptychographic x-ray computed tomography 

      Cuesta-Garcia, Ana Maria; Gomez-de-la-Torre, Maria de los Angeles; Santacruz-Cruz, Maria Isabel; Trtik, Pavel; da Silva, Julio C.; [et al.] (2017)
      Eco-cements are a desirable alternative to ordinary Portland cements because of their lower CO2 footprints. For instance, the manufacture of Calcium SulfoAluminate (CSA) cements is more environmentally friendly than that ...
    • Rietveld quantitative phase analysis with molybdenum radiation 

      Cuesta-Garcia, Ana Maria; Álvarez-Pinazo, Gema; Garcia-Mate, Marta; Santacruz-Cruz, Maria Isabel; García-Aranda, Miguel Ángel; [et al.] (Cambridge Core, 2014)
      Building materials are very complex samples of worldwide importance; hence quantitative knowledge of their mineralogical composition is necessary to predict performances. Rietveld quantitative phase analysis (RQPA) allows ...
    • Synchrotron Pair Distribution Function analyses of Ye’elimite-based pastes 

      Cuesta-Garcia, Ana Maria; García-Aranda, Miguel Ángel; Santacruz-Cruz, Maria Isabel; Gomez-de-la-Torre, Maria de los Angeles; Zea-Garcia, Jesus D. (2018-10-15)
      The study of nanocrystalline phase atomic ordering is intrinsically complicated. The presence of additional crystalline phase(s) exacerbates this challenge. Here, we use the synchrotron pair distribution function (PDF) to ...
    • 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 ...
