Standard Proctor Compaction Test, Liquid Limit, Free Swell Index


In this study, we have observed the effects of sea water and bagasse ash on expansive soil. The sea water is collected from Arabian sea and soil sample is collected from farm at Mula road. Free swell index test was performed on the soil which concluded that it is a highly expansive soil. Tests that were carried out showed major improvement by adding sea water and bagasse ash. Plasticity index is 15.01% for sea water and bagasse ash. Free swell index is significantly reduced by adding sea water and bagasse ash. There is 10.2% increase in specific gravity of soil. There is rise in MDD and OMC by 5.51% and 37.03% respectively by adding the sea water and bagasse ash. Unconfined compressive strength also increased 37.22%.
