what is the role of aggregate crushing value in concrete mix design
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.

Aggregate Crushing Value TestSignificance Test
The aggregates crushing value test should be performed as per IS code 2386 Part IV. First fill the sample aggregate with one-third of the cylindrical measure in three layers. Each layer should be tamped 25times freely. After filling the sample aggregate weigh and record it as W1. Now fill the aggregate in the mould along with the plunger on top.
