COMPACTION AND STRENGTH CHARACTERISTICS OF BLACK COTTON SOIL IN PRESENCE OF HYDROXIDES

The environment is being polluted by humans and in doing so not only air and water but soil is also being contaminated. But increased industrialization, high population growth and uncontrolled exploration of natural resources have resulted in environmental degradation by polluting soil. Geotechnical engineer must concern about the impact of soil due to soil contamination. The industrial foundations and their structure are exposed to a hazardous environment hence their behavior must be considered in the design and execution. Soil pollution results in modification of the physical, chemical and biological properties of soil. There are number of mechanisms through which individual contaminants affect the engineering properties. Including chemical reactions such as dissolution or precipitation and physic-chemical phenomena, affecting intermolecular forces of water solutions. In this paper the behavior of black cotton soil is investigated, essentially containing montomorillonites as principal clay minerals in the presence of inorganic chemical fluids such as pore fluids.
