Aggregate Crushing PlantAggregate Grinding

2014-8-12  Crushed aggregate is produced by crushing quarry rocks, boulders, cobbles, or large-size gravels. Recycled concrete is a viable source of aggregate and has been satisfactorily used in soil-cement, granular subbases, and in new concrete. Aggregate processing consists of crushing, screening, and washing the aggregate to obtain proper cleanliness and size.

2018-4-26  The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Size of recycled aggregates taken for conducting test was between 12.5mm and 10mm. Aggregate crushing value is the percentage of the crushed material passing through 2.36mm sieve in terms of original weight of the sample taken.

Abrasion Test Test to Determine the Abrasion Value ...

2021-8-2  For an aggregate to perform satisfactorily on the pavement, it must be difficult enough to resist the abrasive effect of traffic for a long period of time. Soft aggregates will be quickly crushed into powder, while hard aggregates are quite resistant to crushing. The test will also determine the quality of the aggregate.
