Nov 03, 2013The aggregate sample: The material for the standard test consists of aggregates sized 20.0mm to 25.5mm. The aggregates may be dried at heating at 100 0 -110 0 C for not moe than 4 hours and cooled at room temperature before testing,if necessary.

Methods for determination of aggregate crushing value

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 a 14.0 mm test sieve and retained on a 10.0 mm test sieve. For other size fractions, there is another recommended method.
