Utilization of Human hair fibre to stabilize Black Cotton Soil and Contaminated Soil

Abstract

Land pollution is one of the primary concerns of today. So, conservation of natural resources and utilization of solid waste materials is necessary to deal with the problem of disposal of solid waste. The solid waste can be utilized in the construction and development industries depending on their suitability and attainability. Such a material is human hair fibres which considered as valueless solid waste. These fibres may create environmental problems being non-biodegradable in nature. This paper is focused on utilizing human hair fibre as a stabilizer to modify the properties of soil. It is an analysis to study the influence of Human Hair fibre on the characteristics of black cotton soil and contaminated soil. Human Hair Fibre (natural fibre) is used as a soil strengthening material which can enhance the properties of soil in the field of geotechnical engineering and ground improvement. Human hair fibre is randomly mixed with these soils in the proportion of 0%, 1%, 2%, 3% and 4% by weight of soil. The properties such as free swell index, specific gravity, index properties and strength were determined and compared with non-reinforced soil. The findings show an enhancement in the properties of soil with the inclusion of human hair fibre.
