Aggregate Crushing Value (ACV) can be determined by using a simple formula: This test is repeated once or twice and the average crushing value of the aggregate is determined. The average crushing value in the different tests is the actual crushing value of aggregate.

What is an aggregate crushing value? The resistance capacity of aggregate under gradually applied compression load is known as aggregate crushing value. The test that is performed to measure the relative resistance is called aggregate crushing value test.

The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggregate of aggregate

 — Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load under standardized conditions, and the strength of the aggregate used in road construction is expressed by numerical index.

aggregate crushing value of coarse aggregate. NOTE 1 -The 'aggregate crushing value' gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load.

 — What is the Aggregate Crushing Value Test? The Aggregate Crushing Value (ACV) test conducted on coarse aggregates provides a relative measure of their resistance to crushing under a gradually applied compressive load.

 — The aggregate crushing value test is conducted on coarse aggregates to determine their resistance to crushing under gradually applied compressive load. It is expressed as a percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.

Aggregates comprise a significant proportion of all materials used in the many different construction processes, so it is important to determine the properties of different types of aggregates through effective testing and measurement.

Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements. Crushing value of aggregates indicates its strength.

Hydraulic cement concrete is a cement and water paste in which aggregate particles are embedded. Aggregate is granular material such as sand, gravel, crushed stone, blast-furnace slag, and lightweight aggregates that usually occupies approxi-mately 60 to 75% of the volume of concrete.
