Coconut shell exhibits more resistance against crushing, impact and abrasion ...

Aggregates are the most important constituents in concrete.They give body to the concrete, reduce shrinkage and effect economy. Natural aggregates are inert granular materials such as sand, gravel stone or crushed stone that are used with a binding medium i.e. water, bitumen, portland cement, lime, etc. to form compound materials i.e. asphalt concrete and portland cement concrete.
