Swelling Potential Of Different Expansive Soil Placed At Different Dry Density And Initial Water Content

Abstract

Expansive or swelling soils exist in many part of the world. Such common soils in Australia, India and
South Africa. Show excessive volume changes with increase in water content. Results of this volume increase expansive
soil apply pressure to the structures located or buried in these regions. In this paper study of swelling behavior of
expansive clay is investigate using Consolidometer method. The tests will be carried out on a number of samples
obtained from different part of Saurashtra region Rajkot, Bhavnagar, Jamnagar, Ameli. The remolded samples are
prepared having different initial dry densities with different initial water contents used to study the effect of these
variable parameters on the swelling pressure. It is observed that swell pressures increases with increasing initial dry
density and they decrease with increasing initial water content.
