2.0 THEORY 2 Basically the Aggregate Impact Value (AIV) is the percentage of fines produced from the aggregate sample after subjecting it to a standard amount of impact. The standard amount of impact is produced by a known weight, i.e. a steel cylinder, falling from a set height, a prescribed number of times, onto of aggregate of a standard ... · Procedure: Weigh a certain amount of sample and oven dry it at a temperature of 110-115. Sieve the aggregate sample to discard those which are not residing in our standard limits. Add up the aggregates in the measuring cylinder in three layers, each layer being filled by 1/3 rd part by the tamping rod giving a total of 25 gentle blows per layer ...

 · Step 1 – First, the aggregate sample sieve through 12.5mm sieve and collect it which is retained in 10mm sieve. Step 2 – Now, the sample should be dried through the oven up to 4 hours at 100 deg to 110 deg. Step 3 – Then, the aggregate sample should be filled in the metal cup by 3 layers. Each layer should be tamped 25 times by the ... · Test AIV (Aggregate Impact Value, SS 1974) The AIV (Aggregate Impact Value) is a standard test procedure by which the impact strength of aggregates is tested. Just like in Protodyakonov's test, the material used consists of irregularly shaped particles of the -14 + 10 mm size fraction. The weight of the specimen is A.
