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 the test specimen passing 2.36 mm test sieve .
Aggregate Impact Value Test. 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.
The methods are applicable to aggregates passing at 14.0 mm test sieve and retained on a 10.0 mm test sieve. For smaller size fractions, a recommended method is described in an appendix to this standard. Aggregate sizes larger than 14 mm are not appropriate to the aggregate impact value test.
Impact test The aggregate impact test is carried out to evaluate the resistance to impact of aggregates. Aggregates passing 12.5 mm sieve and retained on 10 mm sieve is filled in a cylindrical steel cup of internal dia 10.2 mm and depth 5 cm which is attached to a metal base of impact testing .

Aggregate Impact Value Test - YouTube. Aug 27, 2009 . Impact value of an aggregate is the percentage loss of particles passing 2.36mm sieve by the application or .
Fines Value, Aggregate Impact Value, and Wet Attrition Value, have been withdrawn from use, and do not now have the status of a national standard. . Index (particle length to width ratio), Impact Value (NOT former BS test, but based on a DIN method), Micro Deval (wear), Freeze Thaw, Resistance to Thermal Shock, and
Procedure to determine Aggregate Impact Value i) The cup of the impact testing machine should be fixed firmly in position on the base of the machine and the whole of the test sample placed in it and compacted by 25 strokes of the tamping rod.
Basically, the aggregates impact value is aggregate which provides a relative measure of the resistance of an aggregate to sudden shock or impact. However, it can be explain as the aggregate crushing value which is defined as a ratio of the weight, of .
In this test we will find out the percentage of the weight of the aggregate sample which gets crushed with respect to the total weight of the sample. This percentage is known as the aggregate impact value and more the aggregate impact value less is the toughness of .
AIVT: Aggregate Impact Value Tests . Aggregate impact value test 1: AIVT_AIV2 % 2DP: 15.03: Aggregate impact value test 2: AIVT_AIV % 1DP: 15: Mean aggregate impact value: AIVT_FRAC : X: 50% between 8mm and 10mm, 25% between 10mm and 11.2mm, 25% between 11.2mm and 12.5mm: Size fraction from which test portion was obtained:

5.14 The Heavy Medium Heavy Impact Value has application to testing the same materials as those tested by the standard, light and medium impact soil testers, for evaluation of a .
This characteristic is measured by 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.
Aggregate Impact Value (BS 812: Part 3) 1. Objective To determine the aggregate impact value in the laboratory 2. Introduction Impact value of an aggregate is the percentage loss of weight particles passing 2.36mm sieve by the application of load by means of 15 blows of standard hammer and drop, under specified test condition.
Aggregate impact value gives the relative strength of aggregates against impact loading.
Aggregate impact value is measured of toughness of aggregate . Toughness is the property of material which indicate its capacity which impact in sudden. Tougher the aggregate more suitable for wearing surface such as road surface.
Aggregate Impact Value AGGREGATE IMPACT VALUE This test is done to determine the aggregate impact value of coarse aggregates as. Aggregate Impact Value AGGREGATE IMPACT VALUE This test is done to determine the aggregate impact value of .
In this test we will find out the percentage of the weight of the aggregate sample which gets crushed with respect to the total weight of the sample. This percentage is known as the aggregate impact value and more the aggregate impact value less is the toughness of .
