To understand the role played by aggregate in the performance of concrete, it is necessary to de fine specific aggregate properties and show their effect on concrete properties.The Role of 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.Why Aggregates have an Important Role in Concrete?,An aggregate is the important material for concrete and also for the construction industry. Concrete is widely used for constructing a house. The significant reality is that some of 70-80% of the amount of concrete volume is taken by the aggregates itself.
