Abstract (en)

[origin: WO2019012234A1] The invention relates to a method for obtaining a compacted material according to which, a) a set of particles of raw materials is mixed with 1% to 50% by weight of a hydraulic binder to form a dry composition, the percentage being relative to the total weight of the dry composition, the particle size distribution of the raw material particles being characterised by a first reference diameter d90 of 50 millimetres or less and a second reference diameter d10 of 0.08 micrometres or more, b) the dry composition formed in step a) is mixed with 1% to 35% by weight of water so as to form a mixed composition, the percentage being relative to the total weight of the dry composition, c) the mixed composition from step b) is vibrated at a frequency of 20 to 80 Hertz and at an amplitude of at least 0.3 millimetres, while a compressive stress is applied to the mixed composition, the value of the applied compressive stress being at least 2 MegaPascal. The invention also relates to a method for obtaining a multilayer compacted material and to the materials obtained according to said methods.
