Abstract
The soil may be classified as cohesive soil and non – cohesive soil. Cohesive soils are black cotton soil or fine soils and non – cohesive soils are sand or coarse soils. The cohesive soils are having property of expansive or shrunk. The black cotton soil is serious problem for geotechnical engineers and it is required to be treated before the construction of superstructures. Grouting and stabilization etc. methods are available for treatment of black cotton soil or expansive soils. In this research paper, review is made on comparative study of stabilization of black cotton soil by natural and artificial fibre. Natural fibres are those which is obtained from nature i.e. coconut fibre, jute fibre, sisal fibre etc. and artificial fibres are those which is manmade i.e. nylon fibre, polypropylene and polyethylene terephthalate etc. Many researchers performed experiments on stabilization of black cotton soil by natural fibre, artificial fibres and combination of different admixture with fibres. The study of liquid limit, plastic limit, standard proctor test and California bearing ratio test is also done for different types of fibre and conclusions are mapped. From study the statement is made that artificial fibre may decompose gradually compare to natural fibres.
