Aggregate impact value W2W1 100 . Soundness Test on Aggregates. To determine the weathering resistance of aggregate soundness test is conducted. If the resistance against weathering is good for aggregate, then it will have high durability. For soundness test we need some chemical solutions namely sodium sulphate or magnesium sulphate.

Aggregate impact value test 1. Aggregate Impact Value TestAim To conduct a test to determine aggregate impact value of coarseaggregate.Note Aggregate Impact Value gives a relative measure of the resistanceof an aggregate to a sudden shock or impact which differs fromcrushing strength.IS 2386 Part IV.ApparatusImpact Testing Machine, Tamping Rod, Sieves 12.5mm, 10mm
Impact test The aggregate impact test is carried out to evaluate the resistance to impact of aggregates. Aggregates passing 12.5 mm sieve and retained on 10 mm sieve is filled in a cylindrical steel cup of internal dia 10.2 mm and depth 5 cm which is attached to a metal base of impact testing machine.
The net weight of aggregate in the measure shall be determined to the nearest gram and this weight of aggregate shall be used the duplicate test on the same material. Test Procedure 1 The impact machine shall rest with out wedging or packing upon the level plate, block or floor, so that it is rigid and the hammer guide columns are vertical.

Aggregate Impact Value Test as per IS 2386 Part-IV 1993. Theory and Scope. The property of a material to resist impact is known as toughness. Due to movement of vehicles on the road, the aggregates are subjected to impact resulting in their breaking down into smaller pieces. The aggregate should therefore have sufficient toughness to resist ...
The aim of aggregate impact test is to determine the relative measure of the resistance of aggregate to sudden shock or impact in which in some aggregate differs from its resistance to a slowly applies compressive load. The property of a material ...

Aggregate impact value test gives an indication of aggregates toughness property i.e. property of a material to resist impact Aggregate impact values are used to classify the stone aggregates with respect to toughness property as given below. Aggregate impact value Toughness Properties 10 Exceptionally tough Strong 10 20 Very tough Strong
As per IS 2386 IV 9377. This Apparatus is used to determine aggregate impact value of coarse aggregate. The hammer of the tester fall freely from 380 mm height on coarse aggregate for 15 times15 sec.the crushed aggregate removed from the cup ,then sieved and weighed.
Aggregate Impact Values, AIVs, below 10 are regarded as strong, and AIVs above 35 would normally be regarded as too weak for use in road surfaces. Aggregate Impact Values and Aggregate Crushing Values are often numerically very similar, and indicate similar aggregate strength properties. Recommended Aggregate Impact Test Values
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
