Clinkering and early age hydration characterization of Belite-Alite Calcium Sulfoaluminate (BACSA) cements
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
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
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 ...
Rheological and hydration characterization of calcium sulfoaluminate cement pastes
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 ...
