of low plastic clay contaminated by industrial effluents

Abstract:
According to the PCSIR (Pakistan council
of scientific and industrial research), there are over
1200 registered industries in Pakistan, which produce
different kinds of products as of 2001-02 EPA report.
Out of these about 90 percent of the industry is leaking
their contaminants into the neighbouring soil. Soil
contamination due to these industrial contaminants has a
direct impact on the Geotechnical properties of the
affected soil and, therefore, on the already existing
structures such as embankment foundations, basements and
clay liners. In addition, it is a common practice in
Pakistan to use contaminated soil as a fill material or
roadway sub-base material due to its availability and
low price. Therefore, it is the need of the time to
investigate the effects of industrial contaminants on
the physical and mechanical properties of the affected
soil. This paper is an effort in predicting the effects
of industrial contaminants on the strength and
deformation characteristics of low plastic clay. Prior
studies have shown the drastic effects on shear strength
and Physio-chemical properties of soils due to certain
effluents. The effects are predicted due to the change
in pore fluid chemistry and sometimes due to the
chemical changes in soil structure. However, the number
of studies are very limited, especially when it comes to
the geotechnical properties of soils. .
