Aggregates for Concrete

aggregate and crushed stone coarse and fine aggregate are produced by crushing natural stone. Crushing, screening, and washing may be used to process aggregates from either sand and gravel deposits or stone quarries. Aggregates may be produced from igneous, sedimentary, or metamorphic rocks, but geological type does not by itself make an aggregate


Aggregate Crushing Value (ACV) test indicates the resistance to crushing under gradually applied crushing load. It is measured as percentage of aggregates passing through 2.36 mm IS sieve after specimen subjected to a compressive load of 40 tonne at the rate 4 tonne per minute and to the weight of aggregates taken.
