Abstract: A process for the manufacturing of a cement substitute may include: mixing an alkaline aluminosilicate containing material with at least one aluminosilicate hydrate containing material, and heating the thus obtained mixture to a calcination temperature of below 800° C. to form a calcined product comprising a reactive amorphous phase having the alkali ions bound therein. The process may further comprise a step of cooling the calcined product to a desired temperature. A cement substitute is obtainable by this process. The cement substitute includes a reactive amorphous phase of co-calcined alkali aluminosilicate containing material and aluminosilicate hydrate, containing material having alkali ions bound therein. The alkali ions are preferably sodium ions.
