Mar 30 2020 The aggregate impact value is defined as a relative measure of the resistance of an aggregate to sudden shock or impact which in some aggregates may differ from its resistance to a slow compressive load.
Feb 26 2013 conclusion aggregate impact value test CGM mining application. Aggregate Impact Value. AGGREGATE IMPACT VALUE This test is done to determine the aggregate impact value of coarse and 230mm length rounded at one end . More detailed.
aggregate impact value is a measure of resistance to sudden impact or shock which may differ from its resistance to gradually applied compressive load. 3. APPARATUS The apparatus of the aggregate impact value test as per IS 2386 Part IV 1963 consists of
Aggregate Impact Value AIV Calculate the mean of the two results to the nearest whole number. Report the mean as the aggregate impact value unless the individual results differ by more than 0.15 times the mean value. In this case repeat the test on two further specimens

Mar 21 2018 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 AIV AIV is the percentage of fines produced from the aggregate sample subjecting it to a standard amount of impact.
Observations and Calculations Calculate the aggregate impact value AIV expressed as a percentage to the first decimal place for each test specimen from the following equation 2 100 1 Where M 1 is the mass of the test specimen in g M 2 is the mass of the material passing the 2.36 mm test sieve in g.
May 21 2020 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 W1W2 100 80 gm 300 gm 26.67 Impact Value Where W1 Weight of the fraction passing through 2.36 mm IS sieve.220 gm

Recommended aggregate impact value Precaution for aggregate impact value test. The sample of aggregate should be sieved in circular motion or movement. The sample aggregate should not be overheated on the oven. The weight of samples and dust should be tamped with the help of a standard size tamping rod.
The aggregate impact value is the proportion of the sample that passes a 2.36 mm sieve after the hammer impacts. European Standards will not contain the 10 per cent fines test or the aggregate impact value test although a different impact test the German Schlagversuch test has been included.
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.

Procedure for aggregate impact value test Aggregate impact value test Machine Take a sample of aggregate and sieve with the help of a 12.5-millimeter sieve and retain it into a 10-millimeter sieve. Sieving should be done in a circular motion. After that sample should be sieved with 10 millimeters sieve and collect in a container.
Aggregate impact value The value of aggregate impact test W1W2100. The value of aggregate impact test should not be more than 45 by weight of aggregates used for concrete other than wearing surface. An impact value 35 is permissible for the bituminous macadam. Maximum permissible impact value for the water bound macadam is 40.
Jan 13 2011 Aggregate Crushing value depends on the shape of agg also. Angular aggregates have a lower ACV than Irregular or rounded aggregates.If we cut a core out of the same agg Say in the quarry and test for compressive strength will give a higher MPa value. It can be considered as a concrete cylinder or UCS tested in lab. So it is hard to corelate
Impact and Crushing Value Aggregate Crushing Value ACV Sets. UTA-0630 Aggregate Crushing Value ACV Set 150 mm BS. UTA-0640 Aggregate Crushing Value ACV Set 75 mm BS. The Aggregate Crushing Value ACV Test Set measures how resistant an aggregate is when being crushed under a gradually applied compressive load.
Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.
Feb 04 2011 The aggregate impact value is expressed as the percentage of the fines formed in terms of the total weight of the sample. 100 W2 Where W1 Original weight of the sample. Aggregate Impact Value W1 W2 Weight of fraction passing 2.36mm IS sieve. Results The mean of the three results is reported as the AIV Aggregate Impact Value of the .
