Reduced CO2 emission and increased energy saving as well as potential use of several industrial by-products as components of clinker-generating raw mix are well-recognized features associated with calcium sulfoaluminate (CSA) clinker manufacture which, compared with that of Portland clinker, requires less limestone in the kiln feed as well as lower burning temperature, fuel consumption and grinding energy in the cement mill.Furthermore, various chemical gypsums and Al2O3-rich by-products like alumina powder and anodization mud were successfully experienced as substitutes for natural gypsum and bauxite, respectively.
