aggregate impact value test table
From the experiment, the value is 29%, 29%, and 29% are close to the maximum allowable limit for good aggregates. Hence, they can be acceptable as their Aggregate Impact value is less than 30%. Aggregate ImpactValues, (AIV's), .
This video demonstrates a aggregate impact value test to determine the aggregate impact value of coarse aggregate. The aggregate impact value gives a relativ.The test aims at looking for the forces required to produce 10% of fine values (i.e. weight of fines aggregates/weight of all aggregates = 10%). This test is very similar to Aggregate Crushing Test in which a standard force 400kN is applied and fines material expressed as a percentage of the original mass is the aggregate crushing value.
The aggregate impact value is the proportion of the sample that passes a 2.36 mm sieve after the hammer impacts. European Standards will not contain the 10 per cent fines test or the aggregate impact value test (although a different impact test, the German Schlagversuch test, has been included).
Observations and Calculations Calculate the aggregate impact value (AIV) expressed as a percentage to the first decimal place for each test specimen from the following equation: Where (𝐴𝐼𝑉) = 𝑀2 × 100 𝑀1 M 1 is the mass of the test specimen (in g); M 2 is the mass of the material passing the 2.36 mm test sieve (in g .
