Abstract
The invention relates to a method for producing supersulfated cement, wherein pozzolanic and hydraulic aluminosilicate components and a calcium-sulfate-alkaline activation complex are mixed together. The calcium-sulfate-alkaline activation complex is produced by carrying out the following successive steps: a first step of mixing 70% by weight of calcium sulfate and 30% by weight of alkaline components; and subsequently; a second step of thermodynamically activating, by hot quenching, the calcium-sulfate-alkaline activation complex; and subsequently; a third step of cold quenching, by rapid mixing, the activated calcium-sulfate-alkaline activation complex with the pozzolanic aluminosilicate components.
