Abstract (en)

[origin: WO2019162605A1] The invention relates to the use of a composition comprising: 40 to 99% of a sulfoaluminous clinker containing, as a phasic composition, in relation to the total weight of the clinker: 5 to 80% of an optionally iron-doped calcium sulfoaluminate phase of formula C4AxFy$z, where x varies from 2 to 3, y varies from 0 to 0.5 and z varies from 0.8 to 1.2; 0 to 25% of a calcium aluminoferrite phase of a composition of general formula C6Ax'Fy', where x' varies from 0 to 1.5 and y' varies from 0.5 to 3; and 10 to 70% of a C2S belite phase; and 1 to 60% of lime; in a method for inerting polluted soil. The invention also relates to a composition for inerting polluted soil, comprising: 70 to 98% of a sulfoaluminous clinker containing, as a phasic composition, in relation to the total weight of the clinker: 5 to 60 % of an optionally iron-doped calcium sulfoaluminate phase of formula C4AxFy$z, where x varies from 2 to 3, y varies from 0 to 0.5 and z varies from 0.8 to 1.2; 0 to 25% of a calcium aluminoferrite phase of a composition of general formula C6Ax'Fy', where x' varies from 0 to 1.5 and y' varies from 0.5 to 3; and 20 to 70% of a C2S belite phase; and 2 to 30% of lime.
