Aggregate impact value test is done to check the toughness of the aggregate by subjecting it to sudden impact load. Usually, aggregate used in road construction is subjected to sudden impact loads due to the Aggregate Impact Given the small aggregate impacts, studies have focused on farm-scale conservation and environmental effects.

Impact Test on Aggregates: Importance and Procedure

The Aggregate Impact Value is calculated as follows: Aggregate Impact Value (AIV) = (W 2 /W 1) * 100. Where W 2 is the total weight of the aggregates passed through the 2.36 mm sieve after the 15 The Aggregate Impact Value (AIV) (M2/M1)x100 19 % 23 %. AIV = M2/M1 * 100%.

2.0 THEORY 2 Basically the 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 from a set height, a prescribed number of times, onto of aggregate of a standard size Aggregate Impact Value (AIV) is the ability of aggregates that resist sudden impact or shock load on it. The characteristic of any material to resist sudden impact is known as toughness. Therefore, this test is performed to check the Toughness of aggregate. This impact load can break aggregate into smaller pieces and which [Solved] Which of the following properties of aggregate is tested by

Based on the test results, the toughness property of the aggregate may be reported as given below. Observations. In each test, the total weight of the sample (weight A) divided by the weight of the fraction passing through 2.36 mm (weight B) gives the aggregate impact value.The aggregate impact value is expressed as the percentage of the fines formed w.r.t the total weight of the sample. Aggregate Impact Value (AIV) = (100*M2)/M1. Where: M1 =Mass of the test specimen. M2 = Mass of Everything you should know about the Aggregate Impact Value (AIV)

The test gives an idea of toughness of the aggregate to resist facture under the impact of moving loads. AIV below 10 are regarded as strong, and AIV’s above 35 would normally be regarded as too weak for use in road surfaces.

This test will determine the toughness of aggregates. In aggregate impact test, there are two samples weigh of 5000g that had two different sizes which is 10mm and 14mm. Both of a size, will be impact by using aggregate impact test. The aggregate will be blowed for 15 time to give the aggregate impact value. After it been blow, the sample willThe greater the AIV value the lower the toughness of the aggregates this will affect possibility of the aggregate to crush.

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.
