Aggregate Impact Value Testing. Jul 14, 2018· Aggregate Impact Value Test AIV test is conducted to determine the Aggregate Impact Value of Coarse aggregate 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 slow compression load.
Types of Testing for Aggregates
TESTING OF AGGREGATE CRUSHING VALUE. Aggregate crushing value is an indior of the crushing resistance of the aggregates when a compressive load is increased. It is tested in accordance with BS 812:110, 1990 and aggregate passing a 14mm test sieve and retained on 10mm sieve are considered for the testing. The allowable range is 17 41.
