Abstract

The present invention relates to a method for inerting clays in hydraulic compositions intended for construction purposes, said method comprising a step of adding to the hydraulic composition or to one of its constituents 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 different chemical nature from the abovementioned chemical natures, and characterised in that its weight average molecular weight is between Mw L and Mw H.
