A process for the treatment of soil(s) and/or industrial waste solids involves press-moulding. Starting materials of controlled different particle size are mixed in order to obtain an optimum compact structure, while eliminating agglomerated structures in the mixture and small quantities of slaked lime and cement and/or sodium silicate as binders are also added. Mixing of the materials is effected by means of a mixer equipped with rollers for a sufficient period of time and then press-moulding is effected in a mould equipped with perforations for drainage under evacuation, thereby obtaining moulded articles such as building blocks. |
