Abstract:

Expansive soils in India are God’s boom to formers but susceptible to detrimental volume changes because of their potential to react to changes in moisture regime, which may causes distortions to the civil engineering structures constructed on these soils, which poses the challenges to the Geotechnical engineers. Block cotton soils are chemically active, their nature and behavior can be controlled through the application of chemical agents, the main advantage by the use of the chemical agents is setting time and curing time can be controlled. This paper emphasizes the effect of AlCl3 on Atterberg’s limits, compaction, soaked CBR and strength characteristics tests of black cotton soil mixing with different percentages, with a view to determine the optimum percentage. In this paper, the test results such as Atterberg limits, Differential Free Swell Index, Compaction characteristics, California Bearing Ratio Values, Strength characteristics and SEM analysis on expansive soils mixed with Aluminum Chloride (AlCl3) in varying percentages of 0.5%, 1.0%, 1.5%, 2.0%, 2.5%, 3.0% and 3.5% of the expansive soil. It is observed that at optimum percentage, i.e., 2.5% AlCl3, there is a marked development in the strength of soil.

Keywords:

Atterberg limits, Aluminum Chloride (AlCl3), Soaked CBR, Unconfined Compression and SEM analysis.
