Lime stabilisation : clay-metal-lime interactions

The literature review identified the current scientific understanding of element and lime interactions with clay minerals and the leaching protocols used to assess contaminant mobility. This understanding formed the basis for the mechanisms postulated for clay-contaminant-lime interactions and the appropriate methods of chemically assessing time-dependent interactions. Two refined clay minerals English China Clay (predominantly kaolinite) and Wyoming Bentonite (predominantly sodium-montmorillonite) were used to assess the time-dependent effects of mineral structural chemistry on clay-contaminant-lime interactions.
