The aggregate impact value is the measure of resistance to sudden impact of shock which may differ from its resistance to gradually applied compressive load. Equipments. The apparatus as per IS 2386 (PartIV) 1993 consist of Standard Reference IS 2720 (Part151965)
Take sieve and sieve the impact aggregate through it. Now take a bowl and measure its weight (X). Put the passed dust of aggregate through sieve into a bowl. Take the weight of the bowl again with the aggregate sample dust (Y). Calculate the weight of passed dust B = (XY)

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 10mm and 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.
The Aggregates Impact Value (AIV) Apparatus is used to determine the aggregate impact value which provides a relative measure of the resistance of an aggregate to sudden shock or impact. The counter fitted to the machine automatically records the number of blows delivered to the sample. AIV is made from steel protected against corrosion.
reported as percentage of wear 4 . In one study the Aggregate Impact Value (AIV) and Los Angeles Abrasion Value (LAAV) of the intact rocks of all locations of Sri Lanka were plotted on a normal scale without considering the type of rock material. It indicates that the LAAV occur between and times of AIV. However the average LAAV for

Step 1 First the aggregate sample sieve through sieve and collect it which is retained in 10mm sieve. Step 2 Now the sample should be dried through the oven up to 4 hours at 100 deg to 110 deg. Step 3 Then the aggregate sample should be filled in the metal cup by 3 layers. Each layer should be tamped 25 times by the
The aggregate impact value should not exceed 45 by weight of the aggregate for concrete other than the wearing surface. The aggregate impact value should not exceed 30 by weight for a concrete wearing surface such as runways roads pavements and floors 10 IS 2386 (Part 4) Average impact value of steel slag is
The aggregate impact value is the proportion of the sample that passes a 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).

India has about kilometers of roads and still the infrastructure of roads is yet to be constructed and maintained. We have utilized this waste aggregate as a replacement of natural aggregate in Granular SubBase (GSB) and bituminous layers in road construction. Indian Road Congress. (1965).

Aggregate Impact Test Procedure for Determining AIV as Per IS 2386 Part4. Description. The Aggregate impact test is used to determine the aggregate impact value (AIV) which provides a relative measure of the resistance of a coarse aggregate to sudden shock or impact. Lower Aggregate Impact values indicate aggregates that are stronger or more

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.
4 days Cement and concrete related building materials are very prominent in the construction sector worldwide. Among the available building materials using lightweight aggregate in combination with cementbased building materials has several advantages high thermal insulation sound absorption and low cost compared with other insulation materials.
The method of aggregate test specifies the procedure for determining the aggregate impact value of coarse aggregate. Aggregate impact value is used to classify the stones in respect of their toughness property as indicated below <10 Exceptionally strong. 1020 Strong. 2030 Satisfactory for road surfacing. 35 Weak for road surfacing
