A Review on Stabilization of Soil Using Coconut Coir Fibre, Lime and PSC

Abstract

Soil is very important in civil engineering constructions. The poor engineering properties of the local soils may present many difficulties for construction and therefore need to improve their engineering properties. Stabilization techniques can be used to improve the properties of soil. Soil stabilization improves various engineering properties e.g., bearing capacity, compressibility, strength, and various other properties of soil. In this research we study the impact of coconut coir fiber to improve the strength of soil. This is aimed at assessing the effects of coconut coir fiber on the stabilization of poor strength soil using 0, 0.5, 1, 2 and 3% of coconut coir fiber by mass of soil sample. In order to achieve our research goal, the following laboratory soil tests must have to carry out on the stabilized soil samples: California Bearing Ratio (CBR), Unconfined Compressive Strength (UCS), Optimum Moisture Content (OMC), Maximum Dry Density (MDD), and Safe Bearing Capacity (SBC).
