Belite hydration at high temperature and pressure by in situ synchrotron powder diffraction
(2020-10-16)
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
(Elsevier, 2020-08-17)
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 ...
Hydration Activation of Alite-Belite-Ye’elimite Cements by Doping with Boron
(2020)
The hydration behavior of two alite-belite-ye’elimite (ABY)
cements has been studied. The production of these materials releases into
atmosphere ∼17% less CO2 compared to Portland cement. The ABY cement
contains alite, ...
Processing and characterisation of standard and doped alite-belite-ye'elimite ecocement pastes and mortars
(2020-02-26)
Here, we report the processing optimisation of two laboratory-prepared alite-belite-ye'elimite ecocements (standard and doped) that release to the atmosphere ~13% less CO2 than Portland Cement during fabrication. The ...
Portland cement pastes analysed by synchrotron and laboratory X-ray imaging
(2020)
Portland Cement (PC) is the most used construction material and the derived building materials have very complex hierarchical microstructures. Quantitative characterization of their microstructures is of paramount importance ...
