ACV and 10% FACT. The tests for Aggregate Crushing Value (ACV) and FACT (10% Fines Aggregate Crushing Test) measure the crushing strength of broken rock. These results do not necessarily relate to the flexural or compressive strength of concrete made with that aggregate, but are a useful index of overall quality.

The requirements of AS 2758.1 - 2009

AS 2758.1 sets out the requirements for the quality of a material source and the properties of the coarse and fine aggregate. Although a number of requirements are nominated, there are some sections that require the use of only one set of the limits shown.

Aggregate Crushing Value Test -Determine Aggregate ...

Aggregate Crushing Value Test – Determine Aggregate Crushing Strength. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions. Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements.

Properties of Aggregates - Civil Snapshot

The aggregates crushing value gives a relative measure of resistance of an aggregate to crushing under gradually applied compressive load. The aggregate crushing strength value is a useful factor to know the behavior of aggregates when subjected to compressive loads.

aggregate crushing value requirements for concrete

The crushing test on aggregate gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. If the aggregate crushing value is less than 10, it signifies an exceptionally strong aggregate. Whereas, if the crushing value is 35 or above, it would normally be considered as weak aggregates.
