METHOD B1 THE DETERMINATION OF THE AGGREGATE .
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

Sieve Analysis of Fine and Coarse Aggregates
Use this test method to determine the particle size distribution of aggregate samples, using standard sieves with square openings. Use Part I to determine a weightbased, drysieve analysis for an aggregate sample. Use Part II to determine a weightbased, sieve analysis for an aggregate sample requiring a washed sieve analysis.
The Effect of Aggregate Properties on Concrete
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. Although aggregate is considered inert filler, it is a necessary component that defines the concrete's thermal and elastic properties and dimensional stability. Aggregate is classified as two different types, coarse and fine.
