Belite calcium sulfoaluminate cement early hydration: citric acid sensitivity.
Koufany, Imane; Santacruz-Cruz, María Isabel; Bescher, Eric P.; García-Aranda, Miguel Ángel
; Gómez-de-la-Torre, María de los Ángeles
(2023)
Three buckets, corresponding to three selected samples, of the same type of belite calcium sulfoaluminate (BCSA) cements have been studied. These cements show very similar elemental and mineralogical compositions, and ... -
Characterisation of SCMs using the R3 test for low carbon cements.
Koufany, Imane; Redondo-Soto, Cinthya; Cuesta-García, Ana María; Santacruz-Cruz, María Isabel; Rodríguez-Ruiz, María Dolores
; García-Aranda, Miguel Ángel
; Gómez-de-la-Torre, María de los Ángeles
[et al.] (2024)
The cement industry is working to reduce its environmental impact by replacing clinker with supplementary cementitious materials (SCMs), including pozzolanic materials. This study examines three types of pozzolanic materials: ... -
Combined use of laboratory X-ray diffraction and microtomography in early age cement hydration.
Cuesta-García, Ana María; Shirani, Shiva; Gómez-de-la-Torre, María de los Ángeles; Santacruz-Cruz, María Isabel
; Morales-Cantero, Alejandro; Koufany, Imane; Redondo-Soto, Cinthya; Salcedo, Inés R.; León-Reina, Laura; García-Aranda, Miguel Ángel
[et al.] (2023)
In situ laboratory X-ray powder diffraction (LXRPD) is widely used for studying cement hydration at early ages. However, this approach has limitations due to the intrinsic characteristics of the main methodologies (flat ... -

Effect of alkanolamines in kaolinitic calcined clays pozzolanic reactivity.
Koufany, Imane; Santacruz-Cruz, María Isabel; Rodríguez-Ruiz, María Dolores
; Bescher, Eric P.; García-Aranda, Miguel Ángel
; Gómez-de-la-Torre, María de los Ángeles
[et al.] (2023)
Five kaolinitic clays with different amounts of kaolinite, ranging between ~70 wt% and ~30 wt%, have been studied to unravel the possible activation effect of alkanolamines on the aluminate fraction of calcined clays. ... -
Materiales puzolánicos para bajar las emisiones de CO2: soluciones locales para un problema global.
Gómez-de-la-Torre, María de los Ángeles; Koufany, Imane; Redondo-Soto, Cinthya; Guirado-Rodríguez, Beatriz; Benjumea-Rejano, Eva M.; Gómez-García, Francisco; Cuesta-García, Ana María; Santacruz-Cruz, María Isabel
; Rodríguez-Ruiz, María Dolores
; García-Aranda, Miguel Ángel
[et al.] (2023)
In recent decades, the cement sector has been looking for solutions to reduce the carbon footprint, being one of the most promising strategies, the replacement of clinker with supplementary cementitious materials, SCMs. ... -
Multimodal study of unaltered cement hydrating pastes: combined high-energy laboratory powder diffraction and microtomography.
Fernández-Sánchez, Jaime; Cuesta, Ana; Shirani, Shiva; Koufany, Imane; Gómez-de-la-Torre, María de los Ángeles; Santacruz-Cruz, María Isabel
; Salcedo, Inés R.; León-Reina, Laura; García-Aranda, Miguel Ángel
[et al.] (2024)
Background: The study of the hydration pathways of Portland cement (PC) and cement blends presents significant challenges due to their multiphase nature and varying fineness. Quantifying the dissolution of initial crystalline ...
