Aggregates Impact Test (AIV) Introduction: Impact value of an aggregate is the percentage loss of weight particles passing 2.36mm sieve by the application of load by means of 15 blows of standard hammer and drop, under specified test condition. 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 ...

The cylinder is placed in impact testing machine which consist a hammer. After placing the cylinder, hammer is raised to 380mm and release freely. Then it will blow the aggregates. Repeat it for 15 such blows. After that take down the sample and aggregate passing through 2.36mm sieve is weighed as w2. Aggregate impact value = (W2/W1) *100 %
