The Effects of Chemical Fluids with Different Dielectric Constants on the Behavior of a Clayey Soil

The physico-chemical forces between the clay particles due to the variation of the dielectric constant of the pore fluids cause to have changes in the structure and the behaviour of the soil. Therefore, it was aimed to investigate the behavior of the clay at the existence of different chemical fluids with various concentrations as the pore fluid. Atterberg limit, shear strength and consolidation tests were performed by using the chemical fluids. Moreover, the optical microscope (OM) views of the specimens obtained from the mixtures in suspension form were examined. According to the experimental results; liquid limit values and consolidation parameters considerably decreased, but cohesion values increased with the increasing chemical fluids concentration and decreasing dielectric constant of pore fluid.
