Methods For Determination Of Aggregate Impact Value Aiv

Aggregate Impact value Test Apparatus ...

· The apparatus of the aggregate impact value test consists of: A testing machine weighing 45 to 60 kg and having a metal base with a plane lower surface of not less than 30 cm in diameter. Level and plane concrete floor of minimum 45 cm thickness are used to support it. The base of the machine should also have provisions for fixing its base.

Determination of Aggregate impact Value (AIV)

Determination of Aggregate impact Value (AIV) 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 higher than 30 the result may be anomalous.

Determination of aggregate Impact value

· Aggregate impact value = W2/ W1 *100. W2 – Weight of aggregate which passes through the IS sieve W1 – Weight of ovendried aggregate. For good quality aggregate, the impact value should not exceed 30% for concrete work and 45 % for base course.
