Study on the Effect of pH on the Atterberg Limits of Kaolinitic and Montmorillonitic Clay
In the present scenario, due to the urbanization and industrialization, much of the air, water and land have become polluted. Any kind of pollution has direct or indirect effect on the properties of soil. So in the present study, the effect of pH on the properties of two soils was studied. In the present study, effect of pH on the Atterberg limits of two soils was investigated using different pore fluids at different pH. Different pore fluids such as NaCl, KCl, NaOH, and KOH at different pH were selected such that pH varying from 6.5 to 13 could be obtained. From the present study, it could be seen that for the same solution with increase in pH the liquid limit was found to increase with decrease in pH both in the case of kaolinite and bentonite. Plastic limit is of lesser importance with regard to pH, both in the case of kaolinite and bentonite. The effect of pH on shrinkage limit in the case of kaolinite and bentonite showed extremely opposite behavior.
