Fig. 18.23 Changes in a quasi-crystal shape before (a, c, e) and after (b, d, f) coming into
contact with NaCl solutions with concentrations of a, b 0.01; c, d 0.30; e, f 1.00 mol/dm 3 NaCl.
The solid line indicates the outline of a quasicrystal before coming into contact with the solution,
and the dashed line indicates the outline of the quasicrystal 15 min after exposure to the solution

18.2.2 Dispersion and Flocculation
Dispersion and flocculation of colloidal earth material are other processes induced
by sodium contamination, comprising both inorganic and organic compounds,
which may affect water transfer properties of the soil-subsurface system. Principal
factors related to clay dispersion-flocculation processes following contact of sodic
