This Apparatus is used to determine aggregate impact value of coarse aggregate. The hammer of the tester fall freely from 380 mm height on coarse aggregate for 15 times/15 sec.the crushed aggregate removed from the cup,then sieved and weighed. The % ratio of the weight passing 2.36mm sieve and weight of oven dried sample is Aggregate Impact value.

Concept and significance of the Aggregate crushing value test. The ' aggregate crushing value test ` gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load …

The Aggregate Impact Value machine has been developed for determining the impact value of aggregates. Manufactured from plated steel against corrosion, a counter fitted to the machine automatically records the number of blows delivered to the sample. The AIV is supplied complete with 75 mm diameter x 50 mm deep, cylindrical measure and steel ...

The cup is fixed firmly in position on the base of the M1 - (M2+M3) 1.0 g 1.9 -1.7 -0.8 the aggregate impact value and more the aggregate impact value less is the hammer machine and the whole of the test sample from 2 32.7 31.5 33.4 To determine the aggregates toughness of the road aggregates and the cylindrical measure is transferred to the cup.

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 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 ...

The crushed aggregate sample which is finer than 2.36 mm is separated and expressed as a percentage of the original weight taken in the mould. The percentage of weight passed through the 2.36m IS sieve is known as Aggregate crushing value.. In situations, when the aggregate value 30 or higher the result may be a mistake and in such cases, the "ten percent fines value" should be determined ...

1. INTRODUCTION ON AGGREGATE IMPACT TESTING MACHINE Ashian Engineers Company India By Ashian Team. 2. Principal: • Toughness is the property of a material to resist impact. Due to traffic loads, the road stones are subjected to the pounding action or impact and there is possibility of stones breaking into smaller pieces.

Aggregate impact value is the ratio of the weight of the fraction passing through 2.36 mm (weight W2) by the total weight of the sample (weight W1 + W2). Aggregate Impact Value = (W2/ (W1+W2)) * 100 = 80 gm / 300 gm = 26.67 (Impact Value) Where, W1= Weight of …

Place the mould in the aggregate impact testing machine and administer 15 numbers of blows of a metal hammer. After that, remove the crushed aggregate and sieve it through a 2.36 mm sieve. The aggregate impact value is measured as % of aggregates passing through the 2.36mm sieve (W2) to the total weight of the sample (W1).
