Chapter 7 Standard Test Procedures Tests For Aggregates And Bricks MAY 2001 Page 7.26 7.6 Aggregate Impact Value 7.6.1 Scope. The aggregate impact value gives a relative measure of the resistance of the aggregate to sudden shock or impact.
Also, it can be defined as the resistance of aggregate to failure by impact load is known as the Impact Value of Aggregate.. The Characteristics of any material to resist sudden impact is known as toughness. When we use aggregate in roads and pavement on which vehicular movement is done and there is a possibility of impact load on aggregate.
The ‘ Aggregate Impact Value’ is the mean of two observations, rounded to a nearest whole number. Precautions. Place the plunger centrally so that it falls directly on the aggregate sample and does not touch the wall of the cylinder in order to ensure that the entire load is transmitted on the aggregates.
09-01-2018· 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. The Indian Standard CODE IS 2386 (Part IV) – 1963 is used for procedure and classification of aggregate by result.

This British Standard, a part of the BS 812 series, describes methods for the determination of the aggregate impact value (AIV) which gives a relative measure of the resistance of an aggregate to sudden shock or impact.
Aggregate Impact Value (AIV) is the percentage of fines produced from the aggregate sample after subjecting it to a standard amount of impact. The standard amount of impact is produced by a known weight, i.e. a steel cylinder, falling a set height, a prescribed number of times, onto an amount of aggregate of standard size and weight retained in a mould.

subjected to a standard loading regime applied through the plunger. This action crushes the aggregate to a degree which is dependent on the aggregate’s crushing resistance. This degree is assessed by a sieving test on the crushed specimen and is taken as the Aggregate Crushing Value. 7.7.1.4 Sampling. The sample used for this test shall be ...
Experiment No. 4: Determination of the aggregate impact value of different coarse aggregate samples. (BS 812) Scope & significance: Aggregate Impact Value The aggregate impact value gives a relative measure of the toughness or the resistance of aggregate sudden shock or impact is not proportional to the resistance to a slowly applied compressive load.

The aggregate impact value is a calculation of the resistance to abrupt impact, bang or shock, which may vary from its resistance to steadily, applied compressive weight. Procedure: The test specimen includes the aggregates of size ranging from 10.0 mm 12.5 mm. Aggregates can be dehydrated by warming them at temperatue of 100-110° C for a timeframe of 4 hours and spread to cool down.
