AN EXPERIMENTAL STUDY ON FIBER CONCRETE USING COCOUNT COIR

Abstract

Investigations to overcome the brittle response and limiting post-yield energy absorption of concrete led to the development of fiber reinforced concrete using discrete fiber within the concrete mass. Out of the commonly used fiber, easily available low cost natural fiber is renewable source materials. Though these fiber are ecologically advantageous. Utilizing coconut coir in concrete production not only solves the problem of disposing this solid waste but also helps conserve natural resources.

The major quantity of wastes generated from agricultural sources are sugarcane molasses, paddy, wheat straw husk, vegetables wastes, food products, tea, oil production, jute fiber, groundnut shell, wooden mill waste, coconut husk, cotton stalks etc.The new and alternative building construction materials developed using agro-industrial wastes have ample scope for introducing new building components that will reduce to an extent the costs of building materials. One such alternative is coconut coir which is a form of agricultural solid wastes. It is one of the most promising agro wastes with its possible uses as pond ash in the production of concrete

This project presents adding and coir fibers to the percentage of 0.5, 1.0, 1.5,  2.0,% to the weight of the concrete. Physical and chemical properties of and coir fibers have been studied. A concrete mix has been designed to achieve the grade of M30 as required by IS 10262-2009. In the phase two contains to determine the Compressive Strength, Split Tensile Strength and Flexural Strength of the concrete at 7, 14 and 28 days.
