Belite hydration at high temperature and pressure by in situ synchrotron powder diffraction
Portland cements are currently used as Oil‐Well‐Cements for the sheath between the metal casing and the borehole. At high pressures and temperatures, the resulting C-S-H gel(s) is partly unstable and it can react to give ...
Calcium aluminate cement conversion analysed by ptychographic nanotomography
Calcium aluminate cements are used for special applications but are nowadays banned for general structural purposes due to the calcium aluminate hydrate conversion, that has led, for concretes fabricated with high water ...
