i want ppt for stabilisation of black cotton soil with copper slag and cement ppt[/size][/font]

Black cotton soils are highly clayey soils
grayish to blackish in color. They contain montmorillonite
clay mineral which has high expansive characteristics. Black
Cotton soils have low shrinkage limit and high optimum
moisture content. It is highly sensitive to moisture changes.
While laying roads or constructing foundations, the sub grade
and its undesirable characteristics need to be modified using a
suitable stabilization technique. Stabilization involves the
methods used for modifying the properties of a soil to improve
its engineering performance, mainly to increase the strength or
stability of soil.
Coimbatore is predominantly blessed with black cotton soil.
The use of waste materials to stabilize the soil and make it as
strong and stable as any other soil is the primary objective of
the project. For this, we need to choose admixtures that may
help in stabilization. The use of waste materials as admixtures
would be the best suitable option. The use of yard waste and
geonails in combination may prove to be an ideal solution for
increasing the strength of the soil and that too in a rapid
manner. Geonails are good stabilizing agents, but they are not
effective on clays due to poor bonding and softness of clay.
Therefore yard waste is used as a catalyst to make the soil
hard enough for intrusion by geonails, which would then
impart high strength in quick time.
