Study on Physical and Mechanical Properties of Dispersive Soil ijtsrd
This paper deals with determination of physical and mechanical properties of dispersive soil. Soil is the foundation material which supports loads from the overlaying structure. Soil dispersivity is mainly due to the presence of exchangeable sodium present in the structure. Dispersive soils are identified by an unstable structure, easily flocculated in water, and very erodible. Using dispersive clay soils in hydraulic structures, embankment dams, or other structures such as roadway embankments can cause serious engineering problems if these soils are not identified and used appropriately. Some important parameters of dispersive soil obtained from laboratory testing are investigated in this paper. Soil sample is taken from Mandalay at about 3ft depth. To determine physical properties of soil, water content determination, specific gravity test, grain size analysis, Atterberg limits test, crumb test. Standard Proctor compaction test, Unconfined Compression Strength UCS test are carried out to determine mechanical properties of soil. According to Unified Soil Classification System, the studied soil is in CH group and group name is lean clay with sand. From crumb test, sample has grade 4. Therefore, the studied soil is highly dispersive.
