Abstract

A large part of central India and a portion of south India are covered with clay soils. These soils have high swelling and shrinkage characteristics and extremely low shear strength. Hence, there is need for improvement of these properties. The practice of using reinforced earth has been well established in soil engineering profession. The use of natural and artificial fibres is a suitable method for soil reinforcing. This method is considered on the condition of optimum mix and suitable moisture. The present study is aimed at determining the behaviour of clay soil reinforced with glass fibre of length 6mm, coir fibre with 12mm length and metal fibre with 20mm length in a random manner. The soil used is a type of clay soil collected from Saibaba colony in Coimbatore district. The composite soils were tested under laboratory conditions and examined for unconfined compression strength (UCS) and compaction test. The fibres are mixed randomly with soil in varying percentages (0.25%, 0.5%, 0.75% and 1%) by dry weight of soil and compacted to maximum dry density at optimum moisture content. The test results indicate a reduction in the maximum dry density and increase in optimum moisture content of soil due to the addition of fibres. It also indicates an improvement in the UCS of soil due to the addition of fibres.
