IMPACT VALUE OF AGGREGATE 1.Objective 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 compressive load. . IS 2386(Part 4):1963 Methods of Test for Aggregates for Concrete- Mechanical Properties. Reaffirmed-Dec 2016 4 . The Aggregate Impact Value (AIV) test, outlined in IS 2386 Part IV, evaluates the impact resistance of aggregates. This is performed with an impact testing apparatus, using a specific procedure and sample preparation method. Aggregates acceptable for wearing surfaces in concrete should not exceed a 45% impact value and for bituminous concrete, 30%. Note 1: A procedure for testing coarse aggregate larger than 19.0 mm [3 / 4 in.] is covered in Test Method C535. Thus coarse aggregates with a maximum size between 19 mm [3 / 4 in.] and 37.5 mm [1 1 / 2 in.] may be tested by Test Method C535 or Test Method C131/C131M. The method of aggregate test specifies the procedure for determining the aggregate impact value of coarse aggregate. Aggregate impact value is used to classify the stones in respect of their toughness property as indicated below: <10% Exceptionally strong. . Aggregate Impact Test Result.
