Study of Saline Water Effect on Geotechnical Properties of High Plastic Soil

In this project work, we observed how the fine-
grained soil properties affect by saline water. In the

laboratory, several tests were conducted. The test was
conducted with and without Sodium Chloride
concentration. By adding Sodium chloride concentration
to the soil, the liquid and plastic limit decreases with
increases its concentration. As we know for the
classification of soil, the liquid limit was an important
factor. So in this project work, we study how salinity
affects liquid limit and how it is carried out for future
work purposes. Also, the plastic limit is affected by saline
water, so plasticity index varies. Here we have discussed
the result and the relative graphs such as Liquid limit vs
NaCl concentration on High plastic soil, Plastic limit vs
NaCl concentration on High plastic soil, OMC vs NaCl
concentration on High plastic soil, MDD vs NaCl
concentration on High plastic soil and also compared the
results of distilled water.
