NOTE 1 -The 'aggregate crushing value' gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggre- gate of 'aggregate crushing value' 30 or higher, the result may be anomalous, and in such cases the 'ten percent fines value' should be determined instead. ...

Aggregate Crushing Value
The aggregate crushing value provides a subjective measure of the resistance of the aggregate crushing in the pressure of the progressively smeared compressive load. When the aggregate crushing value is 30 or greater the outcome can be irregular and in those kind of circumstances the ten percent fines value has to be assessed in its place.

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.

So this aggregate was not strong. 4 CONCLUSION. The ACV value is more than 45% for aggregate used for concrete for non- wearing surface and less than 25% for wearing surface like runways and roadways. The higher the aggregate crushing value, the lower the resistance to crushing under the gradually applied compressive load. 5 REFERENCES

This standard specifies a method for determining the 10% fines aggregate crushing value (FACT value) of a coarse aggregate sample. The FACT value is measured by crushing the aggregate sample and determining the force required to produce 10% fines, which are particles that pass through a 2,360 micrometer sieve. The test can be performed in either dry or wet conditions.
