Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and Portland cement, are an essential ingredient in concrete. When the aggregate is sieved through 4.75mm sieve, the aggregate retained is called coarse aggregate. The maximum size aggregate used may be dependent upon some conditions.
