Aggregate Impact Tester,Impact Testing Machines,Impact

This Apparatus is used to determine aggregate impact value of coarse aggregate. The hammer of the tester fall freely from 380 mm height on coarse aggregate for 15 times/15 sec.the crushed aggregate removed from the cup,then sieved and weighed. The % ratio of the weight passing 2.36mm sieve and weight of oven dried sample is Aggregate Impact value.

Next, the aggregate impact value (AIV) measures the resistance of aggregate to sudden shock or impact, which differ from their resistance to a slowly applied compressive load. Impact value of an aggregate test gives 'an idea' of toughness of the aggregate to resist fracture under the impact of moving load and BS 812 recommended that the AIV should be less than 30.

The aggregate impact value gives a relative measure of the resistance of an aggregate to "sudden shock or impact", which in some aggregates differs from its resistance to a slowly applied compressive load. With aggregate of aggregate impact value (AIV) higher than 30 the result may be anomalous. Also aggregate sizes larger than 14 mm are not appropriate to the aggregate impact test.
