Period #8 Notes: Aggregates - user.engineering.uiowa.edu
In civil engineering materials, the term aggregate denotes granular media. Aggregate can be used in material systems where the individual grains are cemented together with a binder, or they can be used without binder. For example, aggregate is used as a filler in portland cement concrete (pcc) and typically occupies 60-80% of the total volume.
