Aggregate (composite) - Wikipedia

Aggregate properties In most cases, the ideal finished piece would be aggregate. A given application's most desirable quality (be it high strength, low cost, high dielectric constant, or low density) is usually most prominent in the aggregate itself; all the aggregate lacks is the ability to flow on a small scale, and form attachments between particles.
