Advanced synchrotron studies of ye'elimite-based cement pastes
Synchrotron characterization techniques  are being used to study Portland-based cements and recently also CSA and related cements. A key property of these techniques is that they do not require sample preparation, so ...
Early hydration study of standard and doped Alite-Belite-Ye’elimite (ABY) cements through Synchrotron Radiation
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 ...
Clinkering of calcium sulfoaluminate clinkers: polymorphism of ye'elimite
The manufacture of CSA cements is more environmentally friendly than that of OPC as it releases less CO2. This reduction depends on CSA composition and is due to three factors: i) less emissions from decarbonation in the ...
Synchrotron x-ray pair distribution function: A tool to characterize cement gels
Cement matrices contain large amounts of crystalline phases jointly with amorphous and/or nanocrystalline phases. Consequently, their analyses are very challenging. Synchrotron powder diffraction in combination with the ...
Influence of fly ash blending on hydration and physical behavior of Belite-Alite-Ye'elimite cements
A cement powder, composed of belite, alite and ye’elimite, was blended with 0, 15 and 30 wt% of fly ash and the resulting lended cements were further characterized. During hydration, the presence of fly ash caused the ...
