Aggregate definition and Shape, Types, Properties. Aggregates occupy 70 to 80% of the volume of concrete. Physical characteristics and in some cases, the chemical composition of aggregates affect the properties of concrete in its plastic and hardened state. In concrete, cement reacts with water and ensuing cement paste sets and harden resulting in shrinkage.
The Different Types Of Aggregate.
