The determination of aggregate crushing strength is an important test in your civil engineering lab.You know that aggregates are the one the basic unit of building materials.Aggregates are used in several construction processes such as in concrete, road construction etc..

For this reason assessment of strength of the aggregate is made by using a sample of bulk aggregate in a standardized manner. This testing method is known as an aggregate crushing value test. Aggregate crushing value provides the resistance of an aggregate sample to crushing under gradually applied compressive load.
