determination of the aggregate crushing value (ACV) which gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The method is applicable to aggregates passing a14.0mm test sieve and retained on a 10.0 mm test sieve. For other size fractions, a recommended method is described in appendix A.
Get PriceSep 05, 2015With aggregates of aggregate crushing value 30 or higher, the result may be anomalous and in such cases the 10% fines value should be determined and used instead. The standard aggregate crushing test is made on aggregate passing a 12.5 mm IS sieve and retained on 10 mm IS sieve. If required or if the standard size is not available other sizes up to 25 mm may be tested.

An aggregate is typically defined as a coarse aggregate if particles are retained on the No. 8 sieve (see Figure 2.1). The coarse aggregates comprise then the portion of the aggregates that has large particle sizes. An aggregate is defined as a fine aggregate if the material passes the No. 8 sieve (see Figure 2.2).

The tests for Aggregate Crushing Value (ACV) and FACT (10% Fines Aggregate Crushing Test) measure the crushing strength of broken rock. These results do not necessarily relate to the flexural or compressive strength of concrete made with that aggregate, but are a useful index of overall quality. Normal values for ACV range from 14 to 30%, and for
