• ### Aggregate Impact Value Test As Per Is 2386 Partiv 1993

Aug 29, 2019 Aggregate Impact Value Test as per IS 2386 (Part-IV) 1993. Theory and Scope. The property of a material to resist impact is known as toughness. Due to movement of vehicles on the road, the aggregates are subjected to impact resulting in their breaking down into smaller pieces. The aggregate should therefore have sufficient toughness to resist ...

• ### Pdf Determination Of Aggregate Impact Value

Observations and Calculations Calculate the aggregate impact value (AIV) expressed as a percentage to the first decimal place for each test specimen from the following equation 2 () 100 1 Where M 1 is the mass of the test specimen (in g) M 2 is the mass of

• ### Solved The Aggregate Impact Value Of The Aggregate Used

Concept Aggregate Impact Test It is conducted to determine the toughness of the aggregates. For testing, the specimen passing through 12.5 mm sieve but retained on 10 mm sieve is filled in 3 layers with 25 time stamping on each layer and then hammer of 13.5 to 14 kg is dropped freely from a height of 38 cm for 15 blows. Aggregate impact value is then the percentage of fine passing through 2 ...

• ### Experiment On Impact Value Of Stone Aggregate

2021-1-1 Aggregate Impact Value Test as per IS 2386 (Part . 29-08-2019 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 (Part-IV) 1993. Aggregate Impact Value Test . More

• ### Aggregate Impact Test Construction How

Jun 11, 2021 CALCULATION The aggregate impact value is expressed as the percentage of the fines formed in terms of the total weight of the sample. Let the original weight of the oven dry sample be W 1 g and the weight of fraction passing 2.36 mm IS sieve

• ### Aggregate Impact Test Engineering Basic
