Method for producing a hydraulic binding agent

A method of producing a hydraulic binder from the processing of a silicate-containing component with at least one of calcium silicate hydrate- or belite-containing components, the method comprising:

• comminuting a silicate-containing component in at least one comminuting facility to generate a particle size of <100 μm and at least partially break one or more of Si—O—Si bonds and hydrogen bonds in a structure of a surface layer of the silicate-containing component, for surface activation;
• and
• contacting the surface activated silicate-containing component, as a silicate containing carrier substance, with at least one of calcium silicate hydrate- or belite-containing components in a coating facility, resulting in the at least one of calcium silicate hydrate- or belite-containing components accumulating on at least 50% of a surface area of the silicate-containing carrier substance by reactive coating.
