Synchrotron x-ray pair distribution function: A tool to characterize cement gels
Cuesta-García, Ana María; Zea-Garcia, Jesus D.; Londono-Zuluaga, Diana; Gómez-de-la-Torre, María de los Ángeles
; Santacruz-Cruz, María Isabel; García-Aranda, Miguel Ángel[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 ... -
Synthesis and scaled-up of non-active and active Belite-Alite-Ye'elimite clinker (BAY)
Zea-Garcia, Jesus D.; García-Aranda, Miguel Ángel; Gómez-de-la-Torre, María de los Ángeles; Santacruz-Cruz, María Isabel (2017-05-17)
Ordinary Portland cement (OPC) is an environmentally contentious material, as for every ton of OPC produced, ~0.97 tons of CO2 are released. This opens the need of designing new formulations of cements formed by low calcite ... -
Synthesis of active Belite-Alite-Ye'elimite clinker (BAY)
Zea-Garcia, Jesus D.; García-Aranda, Miguel Ángel; Gómez-de-la-Torre, María de los Ángeles; Santacruz-Cruz, María Isabel (2016-06-29)
Ordinary Portland cement (OPC) is an environmentally contentious material, as for every ton of OPC produced, on average, 0.97 tons of CO2 are released. Ye'elimite-rich cements are considered as eco-cements because their ... -
Water-to-cement ratio influence on low-carbon cements performances
Santacruz-Cruz, María Isabel; Zea-Garcia, Jesus D.; Londono-Zuluaga, Diana; Cuesta-García, Ana María; García-Aranda, Miguel Ángel; Gómez-de-la-Torre, María de los Ángeles[et al.] (2019)
Portland Cement (PC) is the most important active ingredient in most of the construction concrete. However, the PC production is associated with a high carbon dioxide release (around 1 ton of CO2 per ton of PC). One approach ... -
X-ray diffraction, cements and environment, three worlds in one
Zea-Garcia, Jesus D.; Gómez-de-la-Torre, María de los Ángeles; Santacruz-Cruz, María Isabel; Londono-Zuluaga, Diana; García-Maté, Marta; Álvarez-Pinazo, Gema; García-Aranda, Miguel Ángel; Cuesta-García, Ana María; León-Reina, Laura; Franco-Duro, Francisco Ignacio; Tobón, Jorge Iván[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 ...
