Abstract
A method for producing components including preparing an aqueous suspension of solids including calcium oxide CaO and silicon dioxide SiO2 with a molar ratio of Ca:Si that is between 0.5:1.0 and 2.5:1.0. Nanocrystalline C—S—H phases are produced by grinding the aqueous suspension and keeping its temperature at or below 100° C. The aqueous phase is separated out from the suspension to form a residue containing the nanocrystalline C—S—H phases. The residued is removed and a powdery product is made by drying the residue. A mold is filled with the powdery product and pressure is applied to form the component. The component is removed from the mold.
