A method for treating polluted soils, includes mixing the soil with a hydraulic binder, wherein the hydraulic binder includes: as the only high-alumina clinker, a high-alumina clinker including more than 80 wt % of mayenite C12A7 phase or a mayenite isotope, the high-alumina clinker making up at least 70 wt % of the weight of the hydraulic binder; and 1 wt % to 30 wt %, relative to the total weight of the binder, of lime.
