Alite hydration mechanism in presence of ye’elimite related to BAY cements
Londono-Zuluaga, Diana; Tobón, Jorge Iván; García-Aranda, Miguel Ángel; Santacruz-Cruz, María Isabel
; Gómez-de-la-Torre, María de los Ángeles
(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 ... -
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, María Isabel
; Gómez-de-la-Torre, María de los Ángeles
[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 ... -
Design and optimisation of new formulations of Belite-Alite Calcium Sulfoaluminate (BACSA) eco-cements
Londono-Zuluaga, Diana; Santacruz-Cruz, María Isabel; Tobón, Jorge Iván; García-Aranda, Miguel Ángel
; Gómez-de-la-Torre, María de los Ángeles
(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 ... -
Hydration study of alite-ye’elimite-anhydrite phases associated to BAY cement
Londono-Zuluaga, Diana; Tobón, Jorge Iván; García-Aranda, Miguel Ángel; Santacruz-Cruz, María Isabel
; Gómez-de-la-Torre, María de los Ángeles
(2017-10-18)
An alternative to decrease CO2 emissions from OPC production consists on the development of a new kind of eco-cements composed by less calcite demanding phases, such as belite and ye'elimite. That is the case of ... -
Hydration study of Belite-Alite Calcium Sulfoaluminate (BACSA) cement blended with fly ash
Londono-Zuluaga, Diana; Tobón, Jorge Iván; García-Aranda, Miguel Ángel; Santacruz-Cruz, María Isabel
; Gómez-de-la-Torre, María de los Ángeles
(2015-10-26)
The main objective of this work is to understand the effect of the addition of fly ash (0, 15 and 30 wt%) in the hydration of a BACSA cement paste (water/cement=0.4) prepared with 12 wt% of anhydrite. The pastes were ... -
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, María Isabel
; Gómez-de-la-Torre, María de los Ángeles
[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. ... -
Synthesis and behavior of Belite-Alite-Ye’elimite (BAY) cement
Londono-Zuluaga, Diana; Tobón, Jorge Iván; García-Aranda, Miguel Ángel; Santacruz-Cruz, María Isabel
; Gómez-de-la-Torre, María de los Ángeles
(2016-06-29)
Ye’elimite based cements have been studied since 70’s years in China, due to the irrelevant characteristics from a hydraulic and environmental point of view. One of them is the reduced fuel consumption, related to the lower ... -
X-ray diffraction, cements and environment, three worlds in one

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 ...
