Relation entre la capacité d'échange cationique et le volume poral dans les sols argileux : incidences sur la morphologie de la phase argileuse à l'échelle des assemblages élémentaires

Abstract : The pore volume resulting from the clay particle fabric was investigated on undisturbed samples from clayey soils. The results show that the variations of this pore volume are related to clay mineralogy, which is characterized by the cation exchange capacity. A morphological model, which takes the measured pore volume variations into account, is proposed for the fabric of the elementary clay particles.
