Aggregate Crushing Value – Significance & Test Procedure
Significance of Aggregate Crushing Value Test. The crushing value test is conducted on aggregates that are used for the construction of roads. Lower crushing value aggregates give much more durability for roads due to its lower crushed fraction under the compression load. The road is subjected to motion pressure continuously.

Gabbro | Properties, Formation, Composition, Uses
Gabbro is a type of intrusive igneous rock that is coarse-grained and dark-colored, typically composed of calcium-rich plagioclase feldspar, pyroxene, and sometimes olivine. It is similar in composition to basalt, which is its extrusive equivalent. Gabbro is typically found in plutonic bodies, such as batholiths and dikes, and is often associated …

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.
Minerals crushing plant boosts production | Agg-Net
The rock extracted is a very hard gabbro with a density of up to 3 tonnes/m3 and a crushing value of 13.1 tonnes. It is also highly abrasive and has a 44–50% silica content. 'This gabbro product represents at least 60% of our production for asphalt plants in Abu Dhabi,' said Mr James. 'It provides us with the highest investment return.
Ten per cent fines value (TFV) — Material Testing Expert
Aggregate Crushing Value = 100(W2/W1) percent where: W2 = Weight of fraction passing the appropriate 2.36 mm sieve. W1 = Weight of dry sample. Normally, the percentage of fines should fall between 7.5 and 12.5. If it falls outside this range, conduct a new test at a load adjusted to bring the percentage of fines within the range of 7.5 to 12.5.

Construction aggregates: evaluation and specification
Aggregate Crushing Value (ACV) – this is the measurement of the resistance of aggregate to crushing by compressive force. A test specimen (10-14mm) is compressed (up to 400 kN) and the proportion of material passing 2.36 mm is the ACV (mean value of two tests). The higher the value the weaker the aggregate.

Stone Aggregate Tests Questions and Answers
Explanation: After the impact test is conducted, the results are obtained in percentage. The aggregate is said to be exceptionally tough when the value is 10%, very tough when the value is in between 10 - 20%, good for pavement surface when the value is in between 20 – 30% and weak if the value is >35%.
