Aggregate impact value test gives an indication of aggregates toughness property i.e. property of a material to resist impact Aggregate impact values are used to classify the stone aggregates with respect to toughness property as given below. Aggregate impact value Toughness Properties lt10 Exceptionally tough Strong 10 20 Very tough Strong
The crushed aggregate is removed from the test specimen and sieve it through the 2.36 mm IS sieve. An impact value is measured as of aggregates passed through the 2.36mm sieve W2 to the total weight of the sample W1. Aggregate impact value The value of aggregate impact test W1W2100
The apparatus used for determining aggregate impact value of coarse aggregates is Impact testing machine conforming to IS 2386 Part IV 1963,IS Sieves of sizes 12.5mm, 10mm and 2.36mm, A cylindrical metal measure of 75mm dia. and 50mm depth, A tamping rod of 10mm circular cross section and 230mm length, rounded at one end and Oven.
Advantages of aggregate impact value test Products As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any sizereduction requirements including, Advantages of aggregate impact value test, quarry, aggregate, and different kinds of minerals
The advantages of aggregates impact test are that the test equipment and procedure are simple, and it can obtain the resistance and impact of stones even in field condition. The test can be done in brief period whether it is at construction site. The specific gravity of aggregates and shape factors will affect the height of the specimens and height of fall of the impact.
The Effect of Aggregate Properties on Concrete Concrete is a mixture of cementious material, aggregate, and water. Aggregate is commonly considered inert filler, which accounts for 60 to 80 percent of the volume and 70 to 85 percent of the weight of concrete.
To evaluate the toughness of a stone i.e. the resistance of the aggregates to fracture under repeated impacts is called Impact Test. This test is done to determine the aggregate impact value of coarse aggregate as per IS 2386 PartIV 1993. Aggregate Impact Value Test as per IS 2386 PartIV 1993. Theory and Scope
Advantages of aggregate impact value test Products. As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any sizereduction requirements including, Advantages of aggregate impact value test, quarry, aggregate, and different kinds of minerals.
Procedure of Aggregate Impact Test The test sample consists of aggregates sized 10.0 mm 12.5 mm. Aggregates may be dried by heating at 100110 C for a period of 4 hours and cooled. i Sieve the material through 12.5 mm and 10.0mm IS sieves.
Aggregate Crushing Value Test l3961u Department of Civil . 16 Jan 2013 Chief advantage of aggregate impact test is that test equipment and the test procedure are quite simple and it determines the resistance to More detailed
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.
Impact Test Fig3 Impact Test Setup. 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 machine.
Aggregate impact value W2W1 100 . Soundness Test on Aggregates. To determine the weathering resistance of aggregate soundness test is conducted. If the resistance against weathering is good for aggregate, then it will have high durability. For soundness test we need some chemical solutions namely sodium sulphate or magnesium sulphate.

The need for impact value test is to find out the toughness of aggregates which is nothing but the ability of aggregates to resist the sudden loading or impact loading. Find out the impact resistance of aggregate is important because, during service life, the aggregates will be actually subjected to this type of load.
Impact test may either be carried out on cylindrical stone specimens as in Page Impact test or on stone 1aggregates as in Aggregate Impact test. The Page Impact test is not carried out nowadays and has also omitted from the revised British Standards for testing mineral aggregates.
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
Chief advantage of aggregate impact test is that test equipment and the test procedure are quite simple and it determines the resistance to impact of stones simulating field condition. The test can be performed in a short time even at construction site or at stone quarry, as the apparatus is simple and portable.
