Volume change behavior of compacted clay due to organic liquids as permeant

To investigate the influence of organic fluids on volume change behavior of compacted clays, two organic chemicals with low and intermediate dielectric constant permeated through compacted specimens of montmorillonite and vermiculite. Swelling and osmotic consolidation tests were performed. Soil index tests were modified to evaluate the effect of organic liquids on clay soils. Results of the investigation showed that pure organic chemicals caused less heaving in comparison with distilled water. Organic liquids caused osmotic consolidation in clay. The plasticity of soil reduced and the settlement time decreased when exposed to organic liquids.
