Aggregates for concrete — Test methods for mechanical and physical properties — Part 3: Determination of aggregate crushing value (ACV)

Granulats pour béton — Méthodes d'essai relatives aux propriétés mécaniques et physiques — Partie 3: Détermination de la valeur de concassage des granulats (ACV)

Abstract / scope

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 sieve. For other size fractions, a recommended method is described in Annex A. The aggregate size fraction taken for this test can also be as per the relevant national standards.

NOTE Minor variations in grading divisions can be allowed in respective national standards.

The method is not suitable for testing aggregates with an aggregate crushing value higher than 30. In such cases, the method described in ISO 20290-4 is applicable.
