Aggregate Definition. "Aggregates are the inert materials that are mixed in fixed proportions with a Binding Material to produce concrete". These act as fillers or volume increasing components on the one hand and are responsible for strength, hardness and durability of the concrete on other hand. I hope that Aggregate Definition will be cleared.
