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 …

This document gives the determination of aggregate crushing value (ACV) of aggregates. This gives a relative measure of the resistance of the aggregate crushing under the gradually applied compressive load. The method is applicable to aggregates passing a 14,0 mm test sieve and retained on a 10,0 mm test

Crushing Characteristics of Coarse Aggregates for …
The conventional aggregate crushing value test (ACVT) applies a load of 400 kN, which results in a compressive stress of 22.65 MPa. This stress level is believed to be far higher than those to which coarse aggregates are subjected under actual compaction and traffic loads. The static load of ACVT may not well reflect the crushing

Recycled Aggregate
Recycled aggregate comes primarily from PCC and AC from road rehabilitation and maintenance, demolition, and leftover batches of AC and PCC. After processing, the rocks retain bits of cement or asphalt. A roadway is built in several layers: pavement, base, and sometimes subbase. The pavement is the surface layer, and is made of PCC or AC.
