Rheological and hydration characterization of calcium sulfoaluminate cement pastes
(2015-05-14)
Calcium sulfoaluminate (CSA) cements are currently receiving a lot of attention because their manufacture produces less CO2 than ordinary Portland cement (OPC). However, it is essential to
understand all parameters which ...
Clinkering and early age hydration characterization of Belite-Alite Calcium Sulfoaluminate (BACSA) cements
(2015-10-26)
In this work, four BACSA clinkers with different compositions (belite ~ 70-55 wt %, alite ~ 10-15 wt % and ye’elimite ~ 10-15 wt %) were synthesized (at laboratory scale). Lime, gypsum, kaolin and sand were used as raw ...
In-situ early age hydration of cement-based materials by synchrotron X-ray powder diffraction
(2015-07-01)
Cement based binders are building materials of worldwide importance. Since these samples are very complex, the knowledge/control of their mineralogical composition are essential to design and predict materials with ...
Hydration studies of ye’elimite by using Ptychographic X-ray nano-tomography
(2015-06-26)
CSA (Calcium SulfoAluminate) cements may have variable compositions but all of them contain ye’elimite(Ca4Al6O12SO4). The manufacture of CSA cements is more environmentally friendly than that of ordinary Portland cements ...
