The results of all of the specimens tested using the 10% Fines Aggregate Crushing test (10%FACT) and Aggregate Crushing Value (ACV) test complied with the South African specifications. However, five of the materials would be rejected on the basis of the ratios of their soaked to dry 10%FACT strengths.

The test requires samples of the aggregate to be subjected to standard load crushing conditions. Multiple layers of presieved materials are tamped 25 times before a 40-ton load is applied at a rate of 4 tons per minute. The crushed aggregate is then sieved, weighed, and compared to the original total weight to provide an aggregate crushing …

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 (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.
