Alite-belite-ye'elimite cements: Effect of dopants on the clinker phase composition and properties
Zea-Garcia, Jesus D.; García-Aranda, Miguel Ángel; Gómez-de-la-Torre, María de los Ángeles
; Santacruz-Cruz, María 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 ... -
A comparative study of experimental configurations in synchrotron pair distribution function
Zea-Garcia, Jesus D.; Gómez-de-la-Torre, María de los Ángeles; García-Aranda, Miguel Ángel
; Cuesta-García, Ana María (MDPI - Publisher of Open Access Journals, 2019-04-25)
The identification and quantification of amorphous components and nanocrystalline phases with very small crystal sizes, smaller than ~3 nm, within samples containing crystalline phases is very challenging. However, this ... -
High pressure and temperature spinning capillary cell for in-situ synchrotron X-ray powder diffraction
Fraga, Edmundo; Yáñez, Armando; Zea-Garcia, Jesus D.; Gómez-de-la-Torre, María de los Ángeles; Cuesta-García, Ana María; Valcárcel-Fernández, Ricardo; Farré-París, Francesc; Malfois, Marc; García-Aranda, Miguel Ángel
[et al.] (2019)
In situ research of materials under moderate pressures (hundreds of bar) is essential in many scientific fields. These range from gas sorption to chemical and biological processes. One industrially important discipline is ... -
Hydration Activation of Alite-Belite-Ye’elimite Cements by Doping with Boron
Zea-Garcia, Jesus D.; Sanfélix, Susana G.; Vallcorba, Oriol; García-Aranda, Miguel Ángel; Santacruz-Cruz, María Isabel
; Gómez-de-la-Torre, María de los Ángeles
[et al.] (2020)
The hydration behavior of two alite-belite-ye’elimite (ABY) cements has been studied. The production of these materials releases into atmosphere ∼17% less CO2 compared to Portland cement. The ABY cement contains alite, ... -
Hydration development and thermal performance of calcium sulphoaluminate cements containing microencapsulated phase change materials
Sanfélix, Susana G.; Zea-Garcia, Jesus D.; Londono-Zuluaga, Diana; Santacruz-Cruz, María Isabel; Gómez-de-la-Torre, María de los Ángeles
; 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 ... -
Local structure and Ca/Si ratio in C-S-H gels from hydration of blends of tricalcium silicate and silica fume
Dapiaggi, Monica; Santacruz-Cruz, María Isabel; Cuesta-García, Ana María; Gómez-de-la-Torre, María de los Ángeles
; Zea-Garcia, Jesus D.; García-Aranda, Miguel Ángel
[et al.] (Elsevier, 2021-03)
At the microscale, C-S-H gels from alite, or neat Portland cements, has a Ca/Si ratio close to 1.80. At the nanoscale, C-S-H is described by a defective tobermorite structure which allows a maximum Ca/Si ratio close to ... -
Multiscale understanding of tricalcium silicate hydration reactions
Cuesta-García, Ana María; Zea-Garcia, Jesus D.; Londono-Zuluaga, Diana; Gómez-de-la-Torre, María de los Ángeles; Santacruz-Cruz, María 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 ... -
Processing and characterisation of standard and doped alite-belite-ye'elimite ecocement pastes and mortars
Zea-Garcia, Jesus D.; Gómez-de-la-Torre, María de los Ángeles; García-Aranda, Miguel Ángel
; Santacruz-Cruz, María Isabel
(2020-02-26)
Here, we report the processing optimisation of two laboratory-prepared alite-belite-ye'elimite ecocements (standard and doped) that release to the atmosphere ~13% less CO2 than Portland Cement during fabrication. The ... -
Rietveld Quantitative Phase Analysis of Oil Well Cement: in Situ Hydration Study at 150 Bars and 150 °C
Fraga, Edmundo; Cuesta-García, Ana María; Zea-Garcia, Jesus D.; Gómez-de-la-Torre, María de los Ángeles; Yañez-Casal, Armando; García-Aranda, Miguel Ángel
[et al.] (MDPI - Publisher of Open Access Journals, 2019-06)
Oil and gas well cements are multimineral materials that hydrate under high pressure and temperature. Their overall reactivity at early ages is studied by a number of techniques including through the use of the consistometer. ... -
Synchrotron Pair Distribution Function analyses of Ye’elimite-based pastes
Cuesta-García, Ana María; García-Aranda, Miguel Ángel; Santacruz-Cruz, María Isabel
; Gómez-de-la-Torre, María de los Ángeles
; 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 ... -
Synchrotron Radiation Pair Distribution Function Analysis of Gels in Cements
Cuesta-García, Ana María; Zea-Garcia, Jesus D.; Londono-Zuluaga, Diana; Gómez-de-la-Torre, María de los Ángeles; Santacruz-Cruz, María 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 ...
