Concrete is an artificial stone manufactured by mixing together coarse and fine aggregates, cement, water and often other components such as cement replacement materials, e.g., pulverised fuel ash, and chemical admixtures, e.g., superplasticisers. The grading of an aggregate defines the proportions of particles of different size in the aggregate.

2019-7-1 as well as on the health of the workers at the sight. To overcome such problems, aggregate can be replaced with coconut shell. In India 13 billion nuts of coconut produced every year which is huge source of coconut shell aggregate. Coconut shell concrete is a mixture of cement sand aggregate and crushed coconut shellaggregate. In this type of concrete the crushed stone aggregate is replaced partially or fully with crushed coconut shell, to utilize the environmental sources and to protect the environment. Thus the main aim is to utilize the coconut shell and to achieve the strength with different percentage of coconut shell aggregate
