بيت /Aggregate Crushing Value Of Brick
Aggregate suitable for use as pipe bedding would display a low compaction fraction, indiing it reaches a state of near full compaction under loose placement. Test Method: Crushing Value: The Aggregate Crushing Value offers a related measure of the resistance of an average to crushing under a compressive load that is gradually applied.
