Effect of Different Densities and Saturation on Unconfined Compressive Strength of Expansive and Yellow Plastic Clay

Abstract

It is well-known that the effects of saturation and maximum dry density can be enormous on the unconfined compressive strength of the soil. This paper asserts the existence of a huge change in the behaviour of the unconfined compressive strength of soil at the combined effect of different densities and saturation conditions. This experiment was done on expansive soil and yellow plastic clay taken from different cities of South Gujarat region in India. The findings show a unique behaviour of the strength of soil at the standard Proctor test’s maximum dry density with the combination of various saturation conditions. A unique upward trend was noticed at the standard Proctor test density at different saturation conditions. Also, different saturation conditions were derived from the experiment.
