The weight of the sample depends on the maximum particle size of the material being inspected. As a rule, a larger top size material the larger the sample. A 25 lb sample of No. 2 coarse aggregate would not be as representative of the material as a 25 lb sample of natural sand. TWO IMPORTANT DEFINITIONS TO REMEMBER
The aggregate crushing value (ACV) of an aggregate is the mass of material, expressed as a percentage of the test sample. which is crushed finer than a 2,36 mm sieve when a sample of aggregate passing the 13,2 mm and retained on the 9,50 mm sieve is subjected to crushing under a gradually applied compressive load of 400 kN. 2 APPARATUS
Aggregate Crushing Value Test Apparatus is used for measuring resistance of an aggregate to crushing. Cylindrical Cell, 150mm internal dia x 130 to 140mm height. Plunger, 148mm dia x 100 to 115mm height.

The percentage mass of fines (passing a BS test sieve) formed in the test is known as the aggregate impact value AIV. higher values are given by weaker materials. For the majority of aggregates the impact value and the crushing value are similar, but brittle materials such as flints yield impact values which are about 5 units higher than ...
and weight of passing material (W2) is expressed as percentage of the weight of the total sample (W1) which is the aggregate crushing value. Aggregate crushing value = W1 W2 100 A value less than 10 signi es an exceptionally strong aggregate while above 35 would normally be regarded as weak aggregates.

The test sample is subjected to a total 15 such blows, each being delivered at an interval of not less than one second. The crushed aggregate is then removed from the cup and the whole of it sieved on the sieve until no further significant amount passes. The fraction passing the sieve is weighed accurate to
