Influence of calcium and silica on hydraulic properties of sodium montmorillonite assemblages under alkaline conditions

Kinsela, Andrew; Tjitradjaja, Alice; Collins, Richard; Waite, David; Payne, T E; MacDonald, Bennett; White, Ian


A sodium-washed montmorillonite was exposed to calcium and silica under alkaline conditions in order to gain insight into possible interactions of engineered clay barriers and cementitious leachates found in many waste storage facilities. The changes in physico-chemical properties of the material were investigated using a combination of dead-end filtration, electrophoresis and scanning electron microscopy. The results show minimal differentiation between unaltered Na-montmorillonite samples at...[Show more]
