Influence of Polymers on the Swelling and Shrinkage Characteristics of Montmorillonite Clays
The objective of this research paper is to create new hydrophobic material using polymers for reducing swelling and shrinkage potential of bentonite (montmorillonite) clay. Three low cost polymers viz. polyvinyl alcohol (PVA) and polyvinyl chloride (PVC) and β-Cyclodextrin is used in present investigation in proportion of 2%, 4% and 8% of dry weight of soil. Series of swelling and shrinkage tests (paraffin-coated wax method) as per IS code was carried out to determine swelling and shrinkage parameters. The selection of polymers is based on clay-polymer interaction and cation exchange capacity. Post analysis of clay-polymer complexes was analyzed to study the change in mineral concentration and exchangeable cations by EDAX and CEC tests. From the results it is concluded PVA reduces swell and shrinkage potential up to 60–65% and with efficient use of soil-chemistry interaction much better results can be obtained for expansive clays.
