All mediums and aggregates are local: Although various norming standards for mediums have been defined (ASTM, US DOT, DIN, ANSI, etc.), those norm/standards are only rough averages: they are specific definitions of terms used in contract specifications sheets, architectural or engineering detail sheets, geotechnical designs, and so forth.

CIVL 1101 - Part 6 - Concrete Agregates

Aggregates generally occupy 70 to 80% of the volume of concrete and therefore have a significant effect on its properties. Strength of concrete and mix design are independent of the composition of aggregate, but durability may be affected. Aggregates are classified based on specific gravity as heavyweight, normal-weight, and lightweight.
