Is Specifiion Of Aggregate Crushing Value

Aggregate Crushing Value Test

The aggregate crushing value is a numerical index of the resistance of an aggregate to crushing under a gradually applied compressive load. It is expressed as the percentage by mass of the crushed (or finer) material obtained when the test sample is subjected to a specified load under standard conditions.

Aggregate Crushing Value Test – Procedure, Result

The crushing value test of aggregate provides the resistance of an aggregate sample to crushing under a gradually applied compressive load. Generally, the test is conducted on aggregate passing 12.5 mm and retained on a 10 mm sieve.
