Abstract

Disclosed is a method and system for producing a hydraulic binder by processing of a silicate-containing component with at least one of calcium silicate hydrate- or belite-containing components. The method includes comminuting the silicate-containing component to a particle sizes of <100 μm, with at least partial breaking of Si—O—Si bonds and/or hydrogen bonds in the structure of the surface layer of the silicate-containing component, for surface activation. The method further includes contacting the comminuted silicate-containing component with calcium silicate hydrate- and/or belite-containing components to cause the calcium silicate hydrate- and/or belite-containing components to accumulate on at least 50% of the surface area of the silicate-containing carrier substance.
