Abstract (en)
[origin: WO2014072337A1] The method according to the invention for producing a hydraulic binding agent by processing a silicate-containing component with components containing calcium silicate hydrate and/or larnite is characterized by the combination of the following two method steps: in the first method step, the silicate-containing component is comminuted in at least one comminution device to particle sizes of <100 µm, wherein Si-O-Si bonds and/or hydrogen bridges in the structure of the surface layer of the silicate-containing component are broken, at least in part, for surface activation; and in the second method step, the silicate-containing component activated in the first step is brought into contact as the silicate-containing carrier material with components containing calcium silicate hydrate and/or larnite in a coating device, wherein the components containing calcium silicate hydrate and/or larnite are enriched on at least 50% of the surface of the silicate-containing carrier material.
