Exposure of bentinite to salt solution: osmotic and mechnical effects

Professor JimeÂnez-Salas offered me the opportunity of further details about my work. If I understand correctly, Professor JimeÂnez-Salas holds , in the tests I have conducted, exposure of the bentonite to a saturated KCl solution might caused a partially irreversible potassium ®xation. the other hand, I have put forward the that such exposure caused a cation that might be reversed by imposing test conditions, for instance by exposing clay to a concentrated NaCl solution. , I stressed that potassium effects are permanent the given test conditions, and that may be permanent under the conditions that occur in nature, but they are not irreversible all conditions. experimental results that I have obtained the meantime seem to conferm that potassium can readily be replaced by sodium ions by action. The phenomenon is observable, from macroscopic point of view, under low values of stress
