Method for obtaining a compacted material and compacted material obtained thereby

A process for obtaining a compacted material according to which,

• a) a dry composition is formed by mixing, on the one hand, a set of raw material particles whose particle size distribution is characterized by a first reference diameter d90 less than or equal to 50 millimeters and a second reference diameter d10 greater than or equal to 0.08 micrometer with, on the other hand, from 1% to 50% of a hydraulic binder, by mass based on the total mass of the dry composition,
• b) said dry composition formed in step a) is mixed with 1% to 35% water, by mass based on the total mass of the dry composition, to form a mixed composition,
• c) the mixed composition obtained in step b) is first vibrated at a frequency between 20 hertz and 80 hertz and at an amplitude greater than or equal to 0.3 millimeter, and then a compressive stress is further applied to said mixed composition during the vibration,
• the value of said applied compressive stress being greater than or equal to 2 megapascals.
