THE INFLUENCE OF ORGANIC SOLUTES ON THE GEOTECHNICAL PROPERTIES OF EXTREMELY PLASTIC CLAYEY SOILS

The behavior of a plastic clayey soil depends on the composite effects of several interacting factors, namely compositional and environmental factors. Compositional factors include: the amount and type of soil minerals, the shape and size distribution of soil particles, adsorbed cautions, and p ore water composition. Environmental factors include: water content, density, confining pressure, fabric, and temperature. Additionally, compositional factor s determine the potential range of values for any soil properties, whereas environmental factors dict ate the actual value. In this report, we have studied the variations involving the geotechnical properties of a highly plastic clayey soil in the presence o f various organic solutes.
