It is man-made product. It is mixture of cement, aggregate, water and admixture. Sand, crushed stone, gravel are aggregates. Mainly aggregates are available natural resources. Taking of aggregates from natural resources affect the environment. In the modern world we use many alternatives of aggregates like waste material and industry products such as fly ash, bottom ash, recycled aggregates, foundry sand, and glass. Apart from above few studies identified that the coconut shell can also be used as aggregate in concrete. Coconut is grown in 86 countries.
