This paper is focused on the use of a CFBC (circulating fluidized bed combustion) fly ash as raw mix component for the synthesis of calcium sulphoaluminate cements. The raw mix composition was designed in order to combine all available sulphate and silica into calcium sulphoaluminate and dicalcium silicate, respectively. To this end additional sources of calcium and aluminium oxides were required: the former was given by pure calcium carbonate; the latter by pure alumina, red mud and/or bauxite.
