Aggregate Properties

Aggregates are porous, and posses a number of voids, some of which are penetrable and some impenetrable. This nature of aggregate makes it difficult to describe one value for its specific gravity. Based on the test methods used, three types of specific gravity are calculated – Bulk, Saturated surface dry, and Apparent.
