A manufacturing method of a ceramic formed body, including: a mixing step in which a raw material for forming a ceramic formed body is dryly mixed, and then, a liquid is added to the obtained dry mixture to wetly mix the mixture; a kneading step in which a mixture obtained in the mixing step is kneaded; an injection step in which supercritical carbon dioxide in the state of supercritical fluid is injected into a kneaded product obtained in the kneading step; and a forming step in which a forming raw material containing the supercritical carbon dioxide obtained in the kneading step and the injection step is extruded to form the ceramic formed body.

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.
