The objective of this research is to develop an understanding of the microstructural aspects of contaminated clays. Specific objectives are: 1. to quantify the physical adsorption of contaminants by clay particles; 2. to quantify the change in physico-chemical forces between clay particles as a result of change in pore fluid chemistry; 3. to investigate the change in fabric resulting from the change in physico-chemical forces; 4. to investigate the change in engineering properties resulting from the above factors. The properties investigated are physical adsorption, stress-strain strength relation, compressibility and hydraulic conductivity.
