Abstract:
A method for inerting clays in sands which are intended for the preparation of hydraulic compositions, the method including a step of adding to the hydraulic composition, or to one of the constituents thereof, a composition which may include at least 50% by weight of a cationic polymer which has a density of cationic charges which is greater than 0.5 meq/g and an intrinsic viscosity which is less than 1 dl/g as an active substance. The hydraulic composition may be a concrete or a mortar.
