Abstract The processing of belite cement clinker in a rotary kiln at about 1000°C CO 2 atmosphere is new recycling option for Autoclaved Aerated Concrete (AAC) waste that otherwise must be landfilled. Waste fine fractions from sorting facility enriched sulfate due to intermixing with plaster have been processed. During clinkering the phase (Ca SiO 4 ) besides technical ellestadite, 10 (SiO 3 (S...
