III. EXPERIMENTAL PROGRAM
For the purpose of stabilization, Black cotton Soil (BC) and NaCl have been used in this study available in Hyderabad.
The soil sample was air dried and grounded to determine the various properties, discussed herewith.
Atterberg Limits: The tests were performed according to IS 2720-Part 15, (1985) on soil passing 425μ sieve. For
saline water, this test was performed at different concentrations.
Specific Gravity: The Specific gravity (G) of the soil has been determined by exploited some density bottle and
pycnometer as per the guidelines provided by IS 2720-Part 3, (1980). The average value has been taken from the three
trials was obtained and the result as shown in the table.
Standard Proctor Compaction Test: The soil sample was oven dried at 110 oC for about 24 hours. Later, as per [8]
standards, the soil is mixed with the various concentrations (0.001 M, 0.01 M and 0.05M) of salt in weight and then this
mix has been compacted in three equal layers with each set of experiments with increasing the water content. Later,
based on the compaction curves plotted for the different mix, optimum moisture content (OMC) and maximum dry
density (MDD) for each test specimens were obtained.
UCC Test: The unconfined compressive strength of the cylindrical shaped specimens (38 mm diameter and 76 mm
length) was determined according to IS: 2720-Part 10, (1991). The cylindrical specimen was placed on the base plate
and the load frame has been fixed without any stress application upon the specimen. Set the dial gauge reading and
