Everything you should know about the Aggregate Impact

The aggregate impact value is expressed as the percentage of the fines formed w.r.t the total weight of the sample. Aggregate Impact Value (AIV) = (100*M2)/M1. Where: M1 =Mass of the test specimen. M2 = Mass of the test specimen passing 2.36 mm test sieve.
