DETERMINATION OF AGGREGATE IMPACT VALUE (AIV) (BS 812112) Scope: This Part of BS 812 describes methods for the determination of the aggregate impact value (AIV) which gives a relative measure of the resistance of an aggregate to sudden shock or impact Principle A test specimen is compacted, in a standardized manner, into an open steel cup The specimen isThe aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load Crushing value is a measure of the strength of the aggregate The aggregates should therefore have minimum crushing value 3 APPARATUS The apparatus of the aggregate crushing value test as per IS: 2386 (Part IV) –DETERMINATION OF AGGREGATE CRUSHING VALUE
