Sieve analysis - Wikipedia

A sieve analysis (or gradation test) is a practice or procedure used (commonly used in civil engineering) to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction of the whole mass.

Aggregate Material - Modern Concrete

Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Our concrete recycling center is also a viable source of aggregate. Our Aggregate processing consists of crushing, screening, and washing the aggregate to obtain proper cleanliness and gradation.
