Abstract - Soil having the property to expand and shrink
the quality of the soil. So were intend to discover the effect of palmyra fiber on the shear strength of black cotton soil.
is known as cohesive soil. Cohesive soil is black cotton soil or fine soil. The major problem for geotechnical engineers is the black cotton soil is required to be treated before the construction of superstructures. There are several methods like Grouting, stabilization, etc for the treatment of black cotton soil. In this project, we investigated the properties of black cotton soil stabilized by palmyra fiber. The experiment covered the index property testes, vane shear test, Direct shear test and unconfined compression test. With the focus on improving the shear strength parameters, soil samples with different combination of palmyra fiber is prepared like 2%,4%,6%, and 8% palmyra fiber blended with natural soil, and the soil sample namely Pfbc-1, Pfbc-2, Pfbc-3, Pfbc-4 were tested under different shear tests. Results were discussed and an optimum proportion of palmyra fiber with black cotton soil is suggested based on the test results performed above.
II. OBJETIVES This paper is mainly aimed to get maximum information about the change in shear strength of black cotton soil available near Coimbatore and also observe the behavior while added with the palmyra fiber. The broad Ares includes:
Study the effect of palmyra fiber on black cotton soil with various proportion
To produce the proper surface layer for backfills without affecting the environment.
Key Words: Black Cotton Soil, Palmyra fiber, PFBC, Compaction tests, Optimum Moisture Content, and shear strength parameter of the Black Cotton Soil.
I. INTRODUCTION 1.1. General A landfill site is also known as a tip dump, rubbish dump, garbage dump, or dumping ground is a site for the disposal of waste materials. A landfill is the oldest and most common form of waste disposal. As Landfills may contain a lot of chemical components it may affect the quality of the soil and also affects the vegetation in the area so by using palmyra fiber the usage of chemicals can be reduced and increase the vegetation in the particular area of landfills. At the same time stability of landfills must be taken into accuracy for future use. A natural fiber that derives from the treatment of the palmyra palm is known as palmyra fiber. A large quantity of palmyra fiber is produced in southern and eastern India. As Using chemicals for the stabilization of the soil results in damage to the quality of the soil and also affects the growth of crops in it. So by using palmyra fiber such conditions can be prevented and soil can be stabilized without affecting
