Aggregate comes in a variety of forms, each with its own characteristics and properties, and these determine its many uses.
Aggregates are often referred to as crushed rock or by their individual geological names. The rock is processed through several stages of crushing and screening to create the final product.
Essentially, primary aggregates can refer to any granular material formed from a natural rock substance, in this instance basalt.
