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 ...
Early hydration study of standard and doped Alite-Belite-Ye’elimite (ABY) cements through Synchrotron Radiation
(2018-07-09)
The manufacturing of ye'elimite-rich cements releases from 15 to 37%, depending on their
composition, less CO2 to the atmosphere than ordinary Portland cement (OPC). BYF cements
containing belite, ye’elimite and ferrite ...
Rietveld quantitative phase analysis with molybdenum radiation
(Cambridge Core, 2014)
Building materials are very complex samples of worldwide importance; hence quantitative knowledge
of their mineralogical composition is necessary to predict performances. Rietveld quantitative phase
analysis (RQPA) allows ...
Ptychographic X-ray computed tomography analysis of cement pastes
(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 ...
