Abstract - Soil stabilisation has become a major
concern in construction engineering. The use of different natural fibres to reinforce soil is an old and ancient idea. Domestic wastes have become a major environmental hazard too. Consequently domestic waste fibre reinforced soil have recently attracted attention in geotechnical engineering .Not only the inclusion of fibres eliminate the problem of waste accumulation ,but also it helps in increasing the bearing strength of soil. In this paper , attempts are made to study the effect of domestic waste fibres, hair and coir, on strength of soil. Key Words: domestic waste fibres, CBR value 1. INTRODUCTION

The objective of this project is to utilize domestic waste fibre for enhancing the bearing strength of soil in an optimal way. Domestic waste requires a large area for its disposal. Human hair fibre(HHF) a non degradable matter is creating a serious environmental hazard. So its use in soil improvement can minimise the problem. In Kerala and other coastal regions of the country, availability of coir fibre is huge. So even after its major applications in coir industries, disposal of the same is also a major concern. This study includes the effect of hair and coir fibres on bearing strength of soil. Fibres randomly mixed in soil samples were tested for its engineering properties by performing CBR tests with varying percentages of fibres.
Fibres were used as an additive to the soil by weight (0.5% ,1% ,1.5% ,2% for hair fibre and 0.25% ,.5% ,0.75% ,1% for coir fibre)to evaluate the strength of soil.
2.METHODOLOGY
California bearing ratio test is used for evaluating the strength of soil.
Soil sample (Red soil) is collected from local sources and geotechnical properties are determined as per IS 2720 (given in Table 1). HHF and Coconut husk fibres were collected from nearby areas and HHF was segregated manually based on length .
