Manufactured in heavy duty form with hardened steel surfaces for minimum wear. The complete assembly is cadmium plated for corrosion protection.
5. The crushed aggregate is remove and pass through size 2.36mm. 6. The fractions passing through and retain is weigh on the sieve. 7. The whole procedure is repeated using the second sample of the mass. Apparatus. The following are the apparatus use during aggregate impact test. Aggregate impact test machine
Aggregate Impact Value (AIV) The apparatus has been designed in a particularly heavy duty form, with specially hardened steel surfaces for minimum wear. The assembly is heavily plated to ensure corrosion resistance and forms a rigid frame around the quick-release trigger mechanism, which ensures an effective free fall of the hammer when released.
The future of the construction aggregate market in Turkey looks good with opportunities in the infrastructure, residential, and non-residential construction industries. The major growth drivers for this market are growth in residential and non-residential construction activities, increasing urbanization, and rising per capita income.

The aggregate impact value of coarse aggregate provides a relative measure of the resistance of an aggregate to sudden shock or impact. The oven dried and accurately weighed aggregates are subjected to a total of 15 blows of specified weight and fall and percentage of fines formed in terms of the total weight of the sample is expressed as the aggregate impact value.
Experiment No. 4: Determination of the aggregate impact value of different coarse aggregate samples. (BS 812) Scope & significance: Aggregate Impact Value The aggregate impact value gives a relative measure of the toughness or the resistance of aggregate sudden shock or impact is not proportional to the resistance to a slowly 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.
Tests are included in British Standards for measurement of the mechanical properties of crushed rock aggregate, including the aggregate impact value (AIV) and aggregate crushing value (ACV) tests (BS 812: 1975). In these tests, samples ranging in size from 10 to 14 mm are subjected to shock and static load.
The apparatus of the aggregate impact value test consists of: A testing machine weighing 45 to 60 kg and having a metal base with a plane lower surface of not less than 30 cm in diameter. Level and plane concrete floor of minimum 45 cm thickness are used to support it. The base of the machine should also have provisions for fixing its base.

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 ...
aggregate impact value. Values obtained in these tests are given in Fig.7. The tested aggregate impact value varies from 6.81% to 12.11%. Aggregate Impact Values (AIV's) below 10 are regarded as strong, and AIV's above 35 would normally be regarded as too weak for use in road surfaces. AIV values for both material tested are exhibit strong enough.
