The behavior and treatment of a clay soil deposited in natural and saline (sodium chloride)
water is studied through experimental tests. A clay soil was deposited in natural water
and water with different concentrations of sodium chloride (40, 80 and 150 g/L) in a
reservoir at lab. The samples were taken from dry deposited soil and they were treated
with 5, 8 and 10% cement. Atterberg limits, compaction and unconfined compression
tests were carried out on the deposited soil and treated soil samples. The results show that
the physical and mechanical behaviors of soil deposited in natural water and salinity
water are not the same and they are function of salt concentration. The results also
indicate that cement can improve the strength of the deposited soil in saline water but this
improvement is not a direct function of salt concentration. In addition, for a constant salt
concentration the strength of treated soil is function of percent of cement and curing time.
Based on SEM (Scanning Electron Microscopy) analysis, it was found that salt
concentrations of 80 and 150 g/L may have prevented the interaction between soil and
cement in the deposited soil.
