    Clinkering of calcium sulfoaluminate clinkers: polymorphism of ye'elimite 

    Gomez-de-la-Torre, Maria de los Angeles; García-Aranda, Miguel Ángel; Santacruz-Cruz, Maria Isabel; Cuesta-Garcia, Ana Maria; Zea-Garcia, Jesus D.; [et al.] (2018)
    The manufacture of CSA cements is more environmentally friendly than that of OPC as it releases less CO2. This reduction depends on CSA composition and is due to three factors: i) less emissions from decarbonation in the ...

    Synchrotron x-ray pair distribution function: A tool to characterize cement gels 

    Cuesta-Garcia, Ana Maria; Zea-Garcia, Jesus D.; Londono-Zuluaga, Diana; Gomez-de-la-Torre, Maria de los Angeles; Santacruz-Cruz, Maria Isabel; [et al.] (2018-07-06)
    Cement matrices contain large amounts of crystalline phases jointly with amorphous and/or nanocrystalline phases. Consequently, their analyses are very challenging. Synchrotron powder diffraction in combination with the ...

    Aluminum Hydroxide Gel Characterization within a Calcium Aluminate Cement Paste by Combined Pair Distribution Function and Rietveld Analyses 

    Cuesta-Garcia, Ana Maria; Ichikawa, Rodrigo U.; Londono-Zuluaga, Diana; Gomez-de-la-Torre, Maria de los Angeles; Santacruz-Cruz, Maria Isabel; [et al.] (Elsevier, 2017-06)
    There are many commercially important multiphase materials which contain amorphous phases, such as cement pastes, porcelains, glass-ceramics or pharmaceutical compounds. However, the analysis of amorphous phase(s) within ...

    Alite hydration mechanism in presence of ye’elimite related to BAY cements 

    Londono-Zuluaga, Diana; Tobón, Jorge Iván; García-Aranda, Miguel Ángel; Santacruz-Cruz, Maria Isabel; Gomez-de-la-Torre, Maria de los Angeles (2019-10-08)
    One alternative to decrease CO2 emissions from ordinary Portland Cement (OPC) production consists on the development of a new kind of eco-cements composed by less calcite demanding phases. That is the case of ...

    In-situ Molibdenum X-ray powder diffraction study of the early hydration of cementitious systems on a humidity chamber 

    Londono-Zuluaga, Diana; Tobón, Jorge Iván; García-Aranda, Miguel Ángel; León-Reina, Laura; Santacruz-Cruz, Maria Isabel; [et al.] (2016-07-06)
    The durability of cement-based construction materials depends on the environmental conditions during their service life. A further factor is the microstructure of the cement bulk, established by formation of cement hydrates. ...

    Pair distribution function studies in cementitious systems 

    Cuesta-Garcia, Ana Maria; Zea-Garcia, Jesus D.; Londono-Zuluaga, Diana; Gomez-de-la-Torre, Maria de los Angeles; Santacruz-Cruz, Maria Isabel; [et al.] (2017-10-24)
    The analysis of amorphous/nanocrystalline phase(s) within cement matrices that contain high amounts of crystalline phase(s) is very challenging. Synchrotron techniques can be very useful to characterize such complex samples.1 ...

    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 ...

    Clinkering and hydration of belite-ye'elimite-alite cement 

    Londono-Zuluaga, Diana; Tobón, Jorge Iván; García-Aranda, Miguel Ángel; Santacruz-Cruz, Maria Isabel; Gomez-de-la-Torre, Maria de los Angeles (Elsevier, 2017)
    Some belite-ye´elimite-ferrite (BYF) cements present low mechanical strengths mainly due to the slow reactivity of belite. A solution to this problem may be the activation of BYF clinkers by preparing them with a coexistence ...

    Influence of fly ash blending on hydration and physical behavior of Belite-Alite-Ye'elimite cements 

    Londono-Zuluaga, Diana; Tobón, Jorge Iván; García-Aranda, Miguel Ángel; Santacruz-Cruz, Maria Isabel; Gomez-de-la-Torre, Maria de los Angeles (2018-10-19)
    A cement powder, composed of belite, alite and ye’elimite, was blended with 0, 15 and 30 wt% of fly ash and the resulting lended cements were further characterized. During hydration, the presence of fly ash caused the ...

    Design and optimisation of new formulations of Belite-Alite Calcium Sulfoaluminate (BACSA) eco-cements 

    Londono-Zuluaga, Diana; Santacruz-Cruz, Maria Isabel; Tobón, Jorge Iván; García-Aranda, Miguel Ángel; Gomez-de-la-Torre, Maria de los Angeles (2015-07-02)
    Belite Calcium SulfoAluminate (BCSA) eco-cements were developed as OPC substitutes since in their production release 22% less CO2 than OPC. BCSA eco-cements contain belite as main phase (>50 wt%) and ye'elimite as secondary ...
