Classification of Aggregates

Heavyweight aggregates: Heavyweight concrete contains aggregates that are natural or synthetic which typically weigh more than 2,080 kg/m 3 and can range up to 4,485 kg/m 3. Heavy weight aggregate is most commonly used for radiation shielding, counterweights and other applications where a high mass-to-volume ratio is desired.
