Study on Osmotic Consolidation and Hydraulic Conductivity Behavior of an Expansive Soil Inundated with Sodium Chloride Solution

Table 6

Results of consolidation test of sample 3 and sample 4 at incremental loading where sample 3 is the soil inundated with distilled water at incremental loading; sample 4 is the soil inundated with salt water and distilled water at the alternate stage of incremental loading.
