This study investigated the use of two kinds of
industrial wastes Ground Granulated Blast Furnace Slag
(GGBS) and Calcium Carbide Residue (CCR) in the
stability of soil. These industrial wastes are generally
dumped or thrown, which produce detrimental effect on
the environment. The use of these wastes as soil
stabilization improves the properties of soil which helps
in various purposes such as designing of pavements,
embankments, etc. and save the environment from the ill
impact. The soil can be treated and stabilized well at a
relatively low cost by using these additives.
From the experimental results, it has been observed that
various properties of soil added with these stabilizers at
certain percentage show remarkable positive changes as
compared to the natural soil obtained. The permeability
of the soil has reduced, which states that it can be used
for the impervious core in Embankments.
In this research, GGBS and CCR were employed in
stabilizing soils, GGBS was fixed at 20% respectively
using index properties tests and then CCR was varied (
i.e. 0.5%, 1.0% and 1.5%). Standard proctor test results
showed general decrease in MDD values and increase in
OMC values which may be obvious as the specific
gravity of the additives is less than that of the soil.
The value of Unconfined Compressive Strength has
increased enabling increase in the bearing capacity of
soil. The increased value of California Bearing Ratio in
both soaked and unsoaked conditions indicates that the
designing of flexible pavements becomes economical by
reducing the thickness of base and sub-base courses.
