Aggregate Crushing Value Test Aggregate Crushing values is a relative resistance of aggregates to crushing under gradually applied compressive load
An aggregate specimen is compacted into a steel cylinder fitted with a no friction plunger The specimen is then loaded via the plunger The load crushes the aggregate to an extent depending on the crushing resistance of the material It is measured by a sieving test on the crushed specimen and it is a measure of the aggregate crushing value (ACV).View Notes aggregate crushing value from CIVIL ENG CIVE3259D at University of Mauritius BRITISH STANDARD Testing aggregates Part 110 Methods for determination of aggregate crushing value.
