Performance of Coconut Shell as Coarse Aggregate in Concrete –A Review

Abstract
The cost of producing concrete has been increasing progressively. Therefore, the demand for utilization of agricultural waste as a partially replacement or admixture inside concrete is also increasing gradually. Many researcher scholars are doing research on agricultural waste such as rice husk, palm oil, corn cobs and coconut shells. Agricultural waste is increasingly being utilized in cement, concrete and other construction materials and provides numerous indirect benefits such as reduction in land fill cost, saving energy and protecting the environment from possible pollution. The aim is to produce concrete with improved properties at a lower cost and to maintain environmental sustainability. In this review paper, the utilization of coconut shell as coarse aggregate in concrete for construction work will be the main focus. Coconut shells can be used as aggregates in concrete. The characteristic properties of coconut shell concrete such as workability, flexural tensile, compressive strength and split tensile strength. This paper attempts to answer whether coconut shell is most suitable to be used in concrete to produce a light weight concrete.
