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.

Construction aggregates are mineral materials used in the production of construction materials such as Portland cement concrete and hot-mix asphalt, and as unbound base courses for pavements. In their primary role as filler in these materials, the volume of aggregates can take up 90 – 95% of asphalt and 70 – 80% of concrete mixtures.
