    Abstract: There is disclosed a polymer-based foam composition comprising a polymer and up to 20 M.-% particles of one or more inorganic particulate materials, based on the total weight of the composition, wherein the one or more inorganic particulate materials comprise less than 20 wt.-% Al, calculated as Al2O3-content. According to one aspect, the one or more inorganic particulate materials comprise phyllosilicates. Also part of the present invention is the use of such polymer-based foam compositions and their method of production.

    Abstract: In a method for obtaining a compacted material, a) a set of particles of raw materials is mixed with 1-50% 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 ≤50 millimetres and a second reference diameter ≥0.08 micrometres, b) the dry composition is mixed with 1-35% by weight of water to form a mixed composition, the percentage relative to the total weight of the dry composition, c) the mixed composition is vibrated ≥0.3 millimetres at 20-80 Hertz, while a compressive stress is applied, the value of the applied compressive stress being at least 2 MegaPascal. Also disclosed is a method for obtaining a multilayer compacted material and to the materials obtained according to the methods.
