Due to rapid urbanization and industrialization, there has been gradual increase in the use of land for various constructional activities. This has resulted in the scarcity of the suitable land (soil) for construction. Now a days the structures are frequently build on the problematic soils. In this study, an attempt has been made to explore the possibilities of using Areca Fibre and Coconut Shell Ash to improve the properties of soil. The experiment is conducted on clayey soil. Coconut Shell Ash is used as a stabilizing agent, and areca fibre is used for reinforcement, in this study. Alternatively, engineers try to utilize these easily available materials in the civil engineering construction based on its feasibility/suitability on their performance. Coconut shell ash is used as an additive material for stabilizing the soil. Stabilizing the soil by adding coconut shell ash improves the soil strength and reduces swell and shrink. Areca Fibre is used as a reinforcing material in soil to impart tensile strength. Because of its high lignin content, it has infield service life of 4 to 10 year and good tensile strength in wet condition. With an addition of areca nut fibers desired properties of soil like compaction, unconfined compression, shear strength, swelling properties can be improved. The reinforcement resists the tensile stress developed within the soil thereby restricting shear failure. Extensive experimental investigations, including compaction, unconfined compression test, Plastic and liquid limit test were conducted on different mix proportions of Coconut shell ash (5%, 10%, 15%, 20%). From the results it is observed that 1.5% areca fibre and 15% coconut shell ash can be used as an effective stabilizing agent in clayey soil.
