      abstract     = {The low-frequency conductivity response of water-saturated
                      packs of glass beads reflects a combination of two
                      processes. One process corresponds to the polarization of
                      the mineral/water interface coating the surface of the
                      grains. The other process corresponds to the Maxwell-Wagner
                      polarization associated with accumulation of the electrical
                      charges in the pore space of the composite medium. A model
                      of low-frequency conductivity dispersion is proposed. This
                      model is connected to a triple-layer model of
                      electrochemical processes occurring at the surface of
                      silica. This model accounts for the partition of the
                      counterions between the Stern and the diffuse layers. The
                      polarization of the mineral/water interface is modeled by
                      the electrochemical polarization model of Schurr for a
                      spherical grain. We take into account also the DC surface
                      conductivity contribution of protons of the sorbed water and
                      the contribution of the diffuse layer. At the scale of a
                      macroscopic representative elementary volume of the porous
                      material, the electrochemical polarization of a single grain
                      is convoluted with the grain size distribution of the porous
                      material. Finally, the Maxwell-Wagner polarization is
                      modeled using the complex conductivity of a granular porous
                      medium obtained from the differential effective medium
                      theory. The predictions of this model agree well with
                      experimental data of spectral induced polarization. Two
                      peaks are observed at low frequencies in the spectrum of the
                      phase. The first peak corresponds to the distribution of the
                      size of the beads and the second peak is due to the
                      roughness of the grains.},
