PROCESS FOR THE PRODUCTION OF A CEMENT SUBSTITUTE
The present invention relates to a process for the manufacturing of a cement substitute, the process comprising the following steps: a) mixing an alkaline aluminosilicate containing material with at least one aluminosilicate hydrate containing material, b) heating the thus obtained mixture to a calcination temperature of below 800°C thereby forming 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. The present invention also relates to a cement substitute obtainable by the process according to the present invention. The cement substitute comprises a reactive amorphous phase of co-calcined alkali aluminosilicate containing material and aluminosilicate hydrate, containing material having alkali ions bound therein. The alkaliions are preferably sodium ions. The present invention also relates to a cement composition containing the cement substitute according to the invention and to a mortar or concrete composition containing such a cement composition.
