• 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, Maria Isabel; Cuesta-Garcia, Ana Maria; Gomez-de-la-Torre, Maria de los Angeles; Zea-Garcia, Jesus D.; [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-Garcia, Ana Maria; Zea-Garcia, Jesus D.; Londono-Zuluaga, Diana; Gomez-de-la-Torre, Maria de los Angeles; Santacruz-Cruz, Maria Isabel; [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 ...
