Utilization of Coconut Shell in Different Forms in Concrete

The rising cost of material is a matter of concern in this developing construction environment. The prices of building material such as cement, sand, gravel etc. are increasing day by day. The reason for increase in cost is high demand and less availability of material. Nowadays, most of the researchers are doing research on the material which can reduce the cost of construction as well as increase the strength. Research on waste material such as fly ash, rice husk, slag and sludge from treatment of industrial and domestic waste water demolished building material is being done. Use of coconut shell in concrete is not only useful economically but also environmentally useful for human being. Coconut shell is one of the main contributors of pollution problem as a solid waste. Coconut shell used as coarse aggregate in concrete encouraged sustainable and environmentally helpful material in the construction field. Since cement rate increases day per day and its availability is decreasing as per time so it can be useful to use coconut shell ash used as substitute of cement in concrete. Coconut shell can be used in the form of powder with epoxy resins or epoxy matrixes in concrete also. Composites are made by combining two or more natural or artificial materials to maximize their useful properties and minimize their weaknesses.
