A Review on Expansive Properties of Dark Cotton Soil

Arnav Chandra | Yashpal Kumar

Abstract: Rapid increase in population and limitation of available land, construction of buildings and other civil engineering structures have to be done on soft soil. The properties of soil remarkably impact the constancy of the design laid on it. Dark Cotton Soil (Expansive soils) have the property of volumetric change when presented to variation in moisture conditions. It is having a swelling and impervious nature with good geotechnical sub grade characteristics. This irregular conduct is basically due the presence of Soil mineral montmorillonite. Physical and geotechnical properties of the soil samples will be studied in the laboratory. The tests such as standard Proctor compaction, specific gravity, grain size analysis direct shear test and consolidation test will be conducted on black cotton soil and sandy soil of the study area. Obtained results will be compared with the Indian standard code (IS).
