Abstract :
[en] Mixing particles of different sizes is an efficient method to increase the density of granular media. While the density of mixtures made of two sizes of glass beads has been highly studied, the dynamics of the compaction process remains poorly investigated. In our study, we measured the typical compaction time for various mixtures depending on the size ratio and the relative fraction of small and large beads. We observed a diverging behaviour of the compaction time close to the percolation threshold and we highlighted a fast compaction dynamics when the size ratio is large enough.
