The Aggregate Crushing Value (ACV) test is a fundamental measure of a material's resistance to crushing under a compressive load. It is widely used in the construction industry to assess the strength of aggregates …
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. Important points to remember. It is recommended that the crushing value of aggregate should be less than 30%.

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.

This test, prescribed by BS 812: Part 110:1990, assesses the resistance of an aggregate to crushing, indicating its ability to withstand compressive loads.
Aggregate Crushing Value (ACV) – this is the measurement of the resistance of aggregate to crushing by compressive force. A test specimen (10-14mm) is compressed (up to 400 kN) and the proportion of material passing 2.36 mm is the ACV (mean value of two tests). The higher the value the weaker the aggregate.
Thus, two tests are made for the same specimen for taking an average value. Calculation: The aggregate crushing value is defined, as a ratio of the weight of fines passing the specified IS sieve to the total weight of the sample expressed as a percentage. Aggregate crushing value = 100 W2 W1 Where, W1 = Total weight of dry sample.
