Impact of Uniaxial Mechanical Perturbation on Structural Properties and Smectite Porosity Features: Ion Exchanger Efficiency and Adsorption Performance Fate

Table 1

Equilibrium void ratio e for the compaction and reswelling data for SWy-Co and SWy-Cd samples. Zero bar corresponds to “free” swelling.
