Design and optimisation of new formulations of Belite-Alite Calcium Sulfoaluminate (BACSA) eco-cements
Belite Calcium SulfoAluminate (BCSA) eco-cements were developed as OPC substitutes since in their production release 22% less CO2 than OPC. BCSA eco-cements contain belite as main phase (>50 wt%) and ye'elimite as secondary ...
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 ...
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 ...
Clinkering and hydration of belite-ye'elimite-alite cement
Some belite-ye´elimite-ferrite (BYF) cements present low mechanical strengths mainly due to the slow reactivity of belite. A solution to this problem may be the activation of BYF clinkers by preparing them with a coexistence ...
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 ...
