The aggregate impact value is the ratio of the weight of the fraction passing through 2.36 mm (weight W2) by the total weight of the sample (weight W1 + W2). Aggregate Impact Value = (W2/ (W1+W2)) * 100 = 80 gm / 300 gm = …
One of the tests that are done on aggregate is impact value test. The amount of patients ...

Tougher the aggregate more suitable for wearing surface such as road surface. Lower the impact value stronger the aggregate, again the impact these for good quality concrete, aggregate with …
Ratio of Impact Value = (W2/W1) x 100 This test must be done at least for two samples. The average value of the two samples is the Impact Value of Aggregate. Lab Test Report Format Conclusion Average of Impact Value of …
Aggregate Impact Value (AIV) Due to the vehicle movement on the road the aggregates are subjected to impact resulting in their breaking down into smaller pieces. The aggregates should, therefore; have sufficient toughness to resist their disintegration due to impact. This characteristic is measured by the impact value test.

The aggregate impact value is a measure of resistance to sudden impact or shock, which may differ from its resistance to gradually applied compressive load. Procedure o f Aggregate …
Home Aggregates Aggregate Impact Value Test Procedure as per IS 2386 Part-4 (1963) with Lab Report, Apparatus List, Formula | AIV Test Aggregate Impact Value Test Procedure as per IS 2386 Part-4 (1963) with Lab Report, Apparatus List, Formula | AIV Test
The need impact value test is used to measure the toughness of aggregates which is nothing but the ability of aggregates to resist the sudden loading or impact loading.. Finding out the impact resistance of aggregate is important because, during service life, the aggregates will be actually subjected to this type of load.For example, aggregates will be subjected to impact …
Procedure of Aggregate Impact value test The test sample: normally aggregates sized 10.0 mm to 12.5 mm. the aggregates should be dried by heating at 100-110 0C for a period of 4 hours and cooled. Sieve the …
AIV = M2/M1 * . Average aggregate impact value of the sample is 21 %. DISCUSSION 1. Give the impact value of a good aggregate to ensure the strength of the. aggregate used in road construction. -Aggregate impact value is measure of toughness of aggregate. Toughness is the property of material which indicate its capacity which impact in sudden.
The main objective of Aggregate impact value test is as following: Aggregates toughness property (property of a material to resist impact) Classify the stone aggregates with respect to …
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 …
AIV = W2/W1*100 Appreciable Percentage of AIV Test <10% = Strong Aggregate, It can be used in any type of construction work. 10 to 20% = Exceptionally Strong aggregate, …
The Aggregates Impact Value (AIV) Apparatus is used to determine the aggregate impact value which provides a relative measure of the …
4. Shape Test on Aggregates (Elongation & Flakiness Index) Flakiness and Elongation Index Test are very important tests to be performed on aggregate in the laboratory. This test gives the percentage of flaky and elongate aggregate present in the total aggregate sample.. Flakiness Index. The flakiness index of aggregate is the % by weight of the particles (aggregates) …
