Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.

“Aggregate Crushing values is a relative resistance of aggregates to crushing under gradually applied compressive load” In situations, when aggregate value 30 or higher the result may be a mistake and in such cases, the “ten percent fines value” should be determined and used instead.

Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load under standardized conditions, and the strength of the aggregate used in road construction is expressed by numerical index .

The aggregate crushing value (ACV) provides relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Two versions available: 150 (standard) and 75 mm dia. The apparatus comprehend cylinder, plunger, base plate, tamping rod and measure.

Aggregate Crushing Value - Aggregate 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. The above mentioned cylinder, plunger and base plate are apt for 3/8Ã‚ to 3/4Ã‚ size aggregate.

Calculate Aggregate Crushing Value. The ratio of the weight of fines formed to the total sample weight in each test shall be expressed as a percentage, the result being recorded to the first decimal place: Aggregate Crushing Value = W B W A × 100. Where, W A is weight of surface-dry sample
