Karthigeyan . S

The free swell of bentonite in presence of salt solution is greater than that of deionized water. The details of the reason is discussed in details in the attached paper. i recommend to you to read the attached paper.

I also recommend you to read the paper as attached herewith.

Emad Maleksaeedi

yes, highly expansive materials such as bentonite usually have higher swelling deformation in presence of salt solution.

Raid R Al-Omari

yes because the ions present in the salt would affect the cation exchange cspacity and the double layer and hence affecting the swelling potential.
