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 ...
