Experimental Determination of the Mechanical Behaviour of Compacted Exfoliated Vermiculite

A series of compacted exfoliated vermiculite samples were prepared, and their mechanical behaviour was experimentally studied. The vermiculite was first exfoliated and after compacted in order to obtain a material with good thermal and mechanical properties. The as‐prepared samples have been tested under compressive loading. Some parameters effect was studied, as the porosity and the type of the compacted exfoliated vermiculite. The samples of this porous media display two steps for the stress–strain behaviour under uniaxial compressive loading, that is initial nonlinear deformation, strain‐hardening ‘pseudo‐platform’ stage.
