A test is recognized with IS:2386 part-IV and conducted to find out the crushing strength of aggregates. The crushing value of aggregate offers a relative measure of resistance against crushing under progressively employed crushing load. Crushing value refers to a measure of the strength of the aggregate.

Aggregate Crushing value test IS Code is 2386-4 (1963): Methods of Test for Aggregates for Concrete. Aggregate Crushing Value Apparatus. Aggregate Crushing Value Apparatus . A 15 cm dia. Steel cylinder with the plunger and base plate. A straight metal tamping rod 16mm in diameter and 45 to 60 cm long rounded at one end.
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.

The crushing value test of aggregate provides the resistance of an aggregate sample to crushing under a gradually applied compressive load. Generally, the test is conducted on aggregate passing 12.5 mm and retained on a 10 mm sieve.
The aggregate crushing value test is normally carried out on aggregates between 10 mm and 12.5 mm in scale. In this test, a ... Figure 1. Map showing source of test aggregate samples 94 .
About 6.5 kg of natural aggregate is required to provide the two test samples. Use less light-weight aggregate. Calculate the percentage of fines generated to the total sample weight. Use the formula: Aggregate Crushing Value = 100(W2/W1) percent where: W2 = Weight of fraction passing the appropriate 2.36 mm sieve. W1 = Weight of dry sample
