Review on Stabilization of Soil Using Coconut Coir Fiber, Lime and Portland Slag Cement

Abstract

The weak structural properties of the black cotton soil can give rise to many adverse situations for construction work and so require improvement of the structural properties. Soil stabilization techniques are used to improve soil properties. The stabilization techniques improve various engineering and bearing properties, such as load-bearing capacity, soil compressibility, soil strength, and many other properties of the soil.
In this study, we are looking into how coconut coir fibre may strengthen soil. With 0 0.5 1, 2, and 3% coconut coir fibre per mass of the black soil samples, the aim of this study is to assess the benefits of coconut coir fibre on the stabilization of low-strength soils. For achieving our research objectives, for this we have to perform the following laboratory tests on the black soil samples: California Bearing Ratio Test (CBR Test), Unconfined Compressive Strength Test (UCS Test), Optimum Moisture Content Test (OMC Test), Maximum Dry Density Test (MDD Test). We will perform the experimental study test on treated and untreated conditions for the soil sample under test and then compare the improvement in the engineering properties of soil achieved by treating it with coconut coir fiber, lime and portland slag cement, so that we can stabilize the soil by waste product which can be effectively used in construction techniques and are economical and environment friendly and thus minimize the adverse effect by chemicals used in chemical stabilization of soil to some extent.
