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 ...
Influence of curing temperature on belite cement hydration: a comparative study with Portland cement
Belite cements (BCs) could be a more sustainable binder than Portland cements (PCs) but adequate knowledge of the hydration features has still to be built. In particular, the mild curing hydration temperature effects have ...
Phase and microstructure evolutions in LC3 binders by multi-technique approach including synchrotron microtomography
Limestone Calcined Clay Cements, LC3, are attracting a lot of attention as it is possible to reduce the clinker factor by 50%, which means a cement CO2 footprint reduction of 40%. This is compatible with maintaining the ...
