Explanation:

An aggregate is an industrial resource which is made up of mixture of sands, gravels and crushed stones.

These aggregates are very useful for a wide range of construction works from road paving, to building construction etc.

Aggregates are very common on the earth crust and they cut across nearly all rock types. The gravels and sands are for example sedimentary rocks. The crushed stones can be a sedimentary rock, a metamorphic gneiss or an igneous granite.

Most of these materials are used because of their durability and ability to tolerate a wide range of adverse environmental conditions.
