Abstract (en)
[origin: WO2022136574A1] The present invention relates to a method for inerting clays in hydraulic compositions intended for construction, said method comprising a step of adding to the hydraulic composition or to one of the constituents thereof at least one clay-inerting agent, characterised in that the clay-inerting agent is a water-soluble polymer comprising acrylamide and/or vinylamine and/or vinylformamide monomer units, and optionally monomer units of a chemical nature different from the abovementioned chemical natures, and characterised in that its weight-average molecular weight is between Mw L and Mw H.
