A Study of the Effects of Injected Chemical Soil Stabilizers on Expansive Clays and Claystones

The effects that organic material has on swell potential and strength of lime-treated expansive clay were determined through laboratory testing. Four soils (one natural and three manufactured) subjected to different laboratory tests were used to analyze the effects of organic material in lime treatment. The laboratory testing program consisted of Atterberg limits, Eads and Grim pH, linear shrinkage, standard compaction, one dimensional swell, and unconfined compression which were used to identify the differences between the physical properties of untreated and treated soils. The soils' physical properties were then graphically and statically analyzed for significant changes. The results indicate that swell potential can practically be reduced to zero, while strength can only be slightly improved. This report also includes soil chemical property data and X-ray diffraction information.
