5. calculation. The ratio of the weight of fines formed to the total sample weight in each test shall he expressed as a percentage, the result being recorded to the first decimal place: Aggregate Impact Value = (B/A) X 100 where A = weight in g of saturated surface - dry sample, B = weight in g of fraction passing through 2.36 mm IS Sieve 6. Detailed Impact Test on Road Aggregates with calculation of Impact value has been shown, also range of aggregate impact value is explained.Toughness is the p. The aggregate impact value is a determining measure of resistance to sudden impact or shock, which may differ from its resistance to gradually applied compressive load. Aim: – To determine Aggregate Impact Value Using Impact Testing Machine. Apparatus: – Impact Testing Machine: – Weight of hammer is 13.5 to 14.0 kg and Height of Fall is .
Usually in large construction works, whether the available aggregate is suitable or not for the work is determined by the impact value test of aggregate. The impact value test of aggregate gives a relative measure of the resistance of an aggregate to sudden shock or impact. Steps by step procedure for Impact value test of [.] Step 6: Calculating the Aggregate Impact Value. The aggregate impact value is calculated by subtracting the weight of the material passing through the 2.36 mm sieve from the original weight of the sample. The result is then divided by the initial weight of the sample and expressed as a percentage.
Impact Testing Machine. Preparation of the Test Sample. The material for the standard test shall consist of aggregate passing a 12.5-mm IS Sieve and retained on a 10-mm IS Sieve, and shall be thoroughly separated on these sieves before testing. . Calculate Aggregate Crushing Value. 2. This test is done to determine the aggregate impact value of coarse aggregates AIV is basically a % ratio of 2.36mm sieved aggregate to 14mm aggregate sieve. The apparatus used for determining aggregate impact value of coarse aggregates is Impact testing machine Sieves of sizes – 14mm, 10mm and 2.36mm,a cylindrical metal measure of .
This property is measured by aggregate impact value test. So that aggregate impact value test is used to determine the relative measure of the resistance of aggregate to sudden shock or impact, which in some aggregate differs from its resistance to a slowly applies 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. If M2 + M3 differs from M1 by more than 1 g discard the results and repeat the test. Calculations. 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 .
