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 mold.The percentage of weight passed through the 2.36m IS sieve is known as the Aggregate crushing value.. In situations, when the aggregate value is 30 or higher the result may be a mistake and in such cases, the “ten percent fines value” should be

Particle size distribution curves of recycled aggregates from concrete pavement crushed by jaw and impact crushers. The jaw crusher produced 85% coarse aggregates (fraction >4.8 mm), whereas the impact crusher produced 82% coarse aggregates. In both cases, the content of particles finer than 0.15 mm was less than 2% mass.

A stone crushing plant is primarily involved in the manufacture of aggregates of various sizes (coarse aggregates, crusher run, rock sand and other fine aggregates) from basalt boulders. Coarse aggregates are usually used in ready mix concrete and asphaltic concrete. Crusher run is used for the bases and sub-bases for road making.
