Stabilization of Contaminated Clays.
Abstract
Three basic clay minerals -- kaolinite, illite and montmorillonite -- were investigated to determine the feasibility of stabilizing or otherwise improving selected engineering properties using lime or cement. Treatment with lime developed greater unconfined compressive strengths, lower densities with increased moisture, and greater resistance to moisture and ice penetration, than with the natural clay minerals. Treating kaoline and illite with cement produced improved strengths and resistance to wet-dry and freeze-thaw cycling. However cement was not effective in improving these properties in montmorillonite because of the clay's fineness, crystallinity and large surface area. (Author)
