Soil Stabilization Using Coconut Coir Fibre
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 9
Abstract
Use of Coconut coir Fibre for improving soil property is advantageous because they are cheap, locally available and eco-friendly. In this study, the stabilizing effect of Coconut coir Fibre (Natural Fibre) on soil properties has been Experimental studied. Keeping this in view an experimental study is conducted on locally available i.e. expensive soil mixed with varying percentage of Coconut coir fibre. Soil samples for California bearing ratio (CBR) tests are prepared at its maximum dry density (MDD) corresponding to its optimum moisture content (OMC) in the CBR mould without and with Coconut coir fibre. The percentage of Coconut coir fibre by dry weight of soil is taken as 0.25%, 0.50%, 0.75% and 1% and corresponding to each Coconut coir fibre content un-soaked and soaked CBR tests are conducted in the laboratory. Tests result indicates that both unsoaked and soaked CBR value of soil increases with the increase in Coconut coir fibre content. Soaked CBR value increases from 3.9 % to 8.6 % and un-soaked CBR value increases from 8.1 % to 13.2 % of soil mixed with 1% Coconut coir fibre. Adding of coconut coir fibre results in less thickness of pavement due to increase in CBR of mix and reduce the cost of construction and hence economy of the construction of highway will be achieved. This is because of composite effect of Coconut coir fibre (Natural Fibre) changes the brittle behaviour of the soil to ductile behaviour.
