ABSTRACT

The soils that make up approximately 1/5^th of the Indian sub-continent are expansive soils, which are the most difficult to work with. These soils swell and shrink, causing problems in the foundation structures. These problems can be resolved by several modification techniques. The present experimental study is to reduce foundation failures by reinforcing the fibres to the expansive soils. Two soils having extreme liquid limits of 58% and 85% in the range were selected and reinforced with Recron 3S fibres. The 1-D consolidation test was conducted for different energy levels with seating pressure of 6.25 kPa to 1600 kPa, which were compacted at MDD and OMC for both natural and reinforced soils. The findings of Cv were estimated for various pressure ranges of plain and fibre-reinforced soils. The magnitude of Cv increased with the addition of fibres and with an increase in pressure when compared with plain soils. The increase in Cv value for the fibre Blended expansive soils induces a significant change in the magnitude of elastic and plastic settlement of soils (the time rate of the settlement gets reduced), thereby achieving economy in terms of time and controlled engineering behaviour.
