Aggregate in Concrete - Concrete Network

Aggregates are generally thought of as inert filler within a concrete mix. But a closer look reveals the major role and influence aggregate plays in the properties of both fresh and hardened concrete. Changes in gradation, maximum size, unit weight, and moisture content can all alter the character and performance of your concrete mix.

The absolute volume of a concrete mix can be determined if the weight and bulk specific gravity of the components are known. For a concrete mix with 90-lbs of coarse aggregate with Gs = 2.65, 60-lbs of fine aggregate with Gs = 2.63, 25-lbs of cement, and 12-lbs of water the absolute volume is computed as follows:
