4D nanoimaging of Portland cement hydration.
Shirani, Shiva; Cuesta, Ana; Díaz, Ana; Trtik, Pavel; Holler, Mirko; Rack, Alexander; Lukic, Bratislav; Brun, Emmanuel; García-Aranda, Miguel Ángel
[et al.] (2024)
Portland cements are environmentally contentious, accounting for ≈8% of the anthropogenic CO2 emissions. The understanding of the cement hydration reactions (dissolution and precipitation processes) is important to contribute ... -
Advanced 3D nanoimaging of cement paste hydration using synchrotron Xray ptychographic tomography
Shirani, Shiva; Cuesta, Ana; Santacruz-Cruz, María Isabel; Gómez-de-la-Torre, María de los Ángeles; Diaz, Ana; Trtik, Pavel; Holler, Mirko; García-Aranda, Miguel Ángel[et al.] (2024-06-25)
Hydration of Portland cements (PC) is a complex phenomenon caused by the presence of multiple components with multi-length scale variability. To investigate this complicated process, state-of-theart 3D nanoimaging ... -
Hydration studies of ye’elimite by using Ptychographic X-ray nano-tomography
Cuesta-García, Ana María; Da Silva, Julio C.; Díaz, Ana; Holler, Mirko; Gómez-de-la-Torre, María de los Ángeles; García-Aranda, Miguel Ángel; Trtik, Pavel[et al.] (2015-06-26)
CSA (Calcium SulfoAluminate) cements may have variable compositions but all of them contain ye’elimite(Ca4Al6O12SO4). The manufacture of CSA cements is more environmentally friendly than that of ordinary Portland cements ... -
Ptychographic X-ray computed tomography analysis of cement pastes
García-Aranda, Miguel Ángel; Cuesta-García, Ana María; Gómez-de-la-Torre, María de los Ángeles; Trtik, Pavel; Díaz, Ana (2019-10-04)
Ptychographic X-ray computed tomography provides 3D electron mass density and attenuationcoefficient distributions of unaltered cement pastes with an isotropic resolution below 100 nm. Thisimaging technique allows ...
