the test piece is a cantilever the aggregate sample sieve through 12.5mm sieve and collect it which is retained in 10mm sieve. Step 2 – Now fill the sample aggregate with one-third of the cylindrical measure in three layers. Each layer should be tamped 25times freely. After filling the sample aggregate
the sample should be dried through the oven up to 4 hours at 100 deg to 110 deg. Step 3 – Then the result being recorded to the first decimal place: Aggregate Impact Value = W B W A × 100. Where meets with BS 812 This characteristic is measured by impact …Calculate Aggregate Impact Value. The ratio of the weight of fines formed to the total sample weight in each test shall he expressed as a percentage
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) – 1963The aggregate which is retained on the 10mm sieve is dried in an oven for a time period of 4 hours at the oven temperature of 100 to 110º C.; The cylindrical measure used for the collection sample filled about 1/3 full with the …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
