Chemically active saturated homoionic clays are considered in a two-phase framework. The solid phase contains the clay particles, absorbed water and salt. The fluid phase contains free water and salt. Water, and possibly salt, can transfer between the two phases. In addition free water may diffuse through the porous medium. In this way a global understanding of the phenomena involved, namely deformation, transfer and diffusion is possible within a unified framework. Reversible chemo-mechanical
