Synthesis and characterization of belite calcium sulfoaluminate cements produced by oxyfuel combustion residues

Abstract: In this work, the possibility of reusing ashes issued by an oxyfuel combustion process (OC) as a source of material in the production of belite calcium sulfoaluminate BCSA cements has been investigated. OF process is one of the most promising combustion technologies for CO2 reduction from power plants. Combustion tests were carried out in an oxyfuel bubbling fluidized bed pilot plant. Four BCSA clinker-generating raw mixes were heated in a laboratory electric oven in the temperatures range 1150°-1350°C: one in… Show more

“…BCSA cements represent a promising alternative to OPC as they exhibit comparable physical and mechanical properties [26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41]. The technical behavior of BCSA cements mostly depends on the ability of C 2 S and C 4 A 3 $ (their main components) to generate, upon hydration, CSH (calcium silicate hydrates, at medium and longer periods) and C 6 A$ 3 H 32 (ettringite, at early ages), respectively.…”
