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; Turrillas, Xavier; García-Aranda, Miguel Ángel[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 ... -
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 ... -
Hydration development and thermal performance of calcium sulphoaluminate cements containing microencapsulated phase change materials
Sanfelix, Susana G.; Zea-Garcia, Jesus D.; Londono-Zuluaga, Diana; Santacruz-Cruz, Maria Isabel; Gomez-de-la-Torre, Maria de los Angeles; Kjøniksen, Anna-Lena[et al.] (2020-03-24)
Microencapsulated phase change materials (MPCM) incorporated in buildings walls can reduce indoor temperature fluctuations, conserving energy and enhancing thermal comfort. MPCM were incorporated in calcium sulphoaluminate ... -
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 ... -
Multiscale understanding of tricalcium silicate hydration reactions
Cuesta-Garcia, Ana Maria; Zea-Garcia, Jesus D.; Londono-Zuluaga, Diana; Gomez-de-la-Torre, Maria de los Angeles; Santacruz-Cruz, Maria Isabel; Vallcorba, Oriol; Dapiaggi, Monica; Sanfélix, Susana G.; García-Aranda, Miguel Ángel[et al.] (Nature Publishing Group, 2018-06)
Tricalcium silicate, the main constituent of Portland cement, hydrates to produce crystalline calcium hydroxide and calcium-silicate-hydrates (C-S-H) nanocrystalline gel. This hydration reaction is poorly understood at ... -
Synchrotron Radiation Pair Distribution Function Analysis of Gels in Cements
Cuesta-Garcia, Ana Maria; Zea-Garcia, Jesus D.; Londono-Zuluaga, Diana; Gomez-de-la-Torre, Maria de los Angeles; Santacruz-Cruz, Maria Isabel; Vallcorba, Oriol; García-Aranda, Miguel Ángel[et al.] (MDPI, 2017)
The analysis of atomic ordering in a nanocrystalline phase with small particle sizes, below 5 nm, is intrinsically complicated because of the lack of long-range order. Furthermore, the presence of additional crystalline ... -
Tailored setting times with high compressive strengths in bassanite calcium sulfoaluminate eco-cements
García-Maté, Marta; Londono-Zuluaga, Diana; Gomez-de-la-Torre, Maria de los Angeles; Ramirez-Losilla, Enrique; Cabeza-Diaz, Aurelio; García-Aranda, Miguel Ángel; Santacruz-Cruz, Maria Isabel[et al.] (Elsevier, 2016-09)
This work deals with the hydration of a calcium sulfoaluminate (CSA) eco-cement prepared with bassanite and different additives (type and content) at a fixed water/CSA ratio of 0.5. Pastes prepared with bassanite show high ...
