Aggregate Crushing Value Test

Aggregate Crushing Value (ACV) can be determined by using a simple formula: This test is repeated once or twice and the average crushing value of the aggregate is determined. The average crushing value in the different tests is the actual crushing value of aggregate.

Determination the Crushing Value of Aggregate test

The aggregate sample undergoes a specified load under standardized conditions, producing a percentage mass of fines, which is then calculated as a ratio of the weight of fines passing through specified sieves to the total weight of the sample to determine the crushing value of the aggregate. The lower the crushing value, the stronger the aggregate.

Aggregate Crushing Value Test

Procedure The aggregate sample: The material for the standard test consists of aggregates sized 10.0 mm to 12.5 mm.The aggregates must be in a surface dry condition before testing. The aggregates may be dried by heating at 100 oC – 110 o C for not more than 4 hours and cooled to room temperature before testing, if necessary.

Ten per cent fines value (TFV) — Material Testing Expert

Aggregate Crushing Value = 100(W2/W1) percent where: W2 = Weight of fraction passing the appropriate 2.36 mm sieve. W1 = Weight of dry sample. Normally, the percentage of fines should fall between 7.5 and 12.5. If it falls outside this range, conduct a new test at a load adjusted to bring the percentage of fines within the range of 7.5 to 12.5.
