Abstract
Physico-chemical interactions play a key role in understanding the behaviour of clay soils in wide range of geotechnical and geoenvironmental engineering applications. Its significance on the behaviour of clay soils reconstituted from slurries has been well demonstrated in the literature. Compacted soils and natural soil deposits which are unsaturated also come in contact with contaminants in these applications. Therefore, this paper examines the effect of physico-chemical factors on the structure, compressibility and collapse behaviour of compacted soil. Physico-chemical effects were incorporated using sodium chloride and calcium chloride salt solutions as pore fluid and interacting fluid in different combinations. The changes in the soil structure due to the physico-chemical changes were studied using scanning electron micrographs. The experimental results were analysed and discussed with the aid of Barcelona expansive model (BExM) framework in this paper.
