Aggregates types and their uses BELLY DUMP, END

The most common types of aggregates are gravel, crushed stone, and sand. The two of the widely used material produced with the help of aggregates are asphalt concrete and Portland cement concrete. The properties of aggregates like color, surface texture, abrasion resistance; porosity, polishing, and absorption capacity depend on the parent rock.

Heavyweight Aggregates for Heavyweight Concrete

Heavyweight aggregates as it can be seen from the name is an aggregate that posses relatively high density and it is fundamental in a situation that high density concrete is necessary.
