Aggregate Crushing Value SignificanceTest Procedure
The aggregates crushing value test should be performed as per IS code 2386 Part IV. First, fill the sample aggregate with one-third of the cylindrical measure in three layers Each layer should be tamped 25times freely. After filling the sample aggregate, weigh and record it as W1. Now fill the aggregate in the mould along with the plunger on top.

Aggregate Crushing Value Test The Constructor
The ratio of weight of fines formed to the weight of total sample in each test shall be expressed as a percentage, the result being recorded to the first decimal place. Aggregate crushing value = (W2 x 100) / (W1-W) W2 =Weight of fraction passing through the appropriate sieve W1-W =Weight of surface dry sample.

Aggregate crushing value test Civil Concept
The aggregate sample is collected from the site. The sample is sieved. This can be done either manually or on a sieve shaker. The aggregate passing through 12.5 mm IS sieve and retained on 10 mm IS sieve is selected for a standard test. The sample is dried and allowed to cool to room temperature. 3 kg of dried sample is weighed.

Aggregate Crushing value test procedure Civil4M
Oct 04, 2020The aggregate crushing value is an indirect measure of crushing strength of the aggregates. Low aggregate crushing value indicates strong aggregates, as the crushed fraction is low. Thus the test can be used to assess the suitability of aggregates with reference to the crushing strength for various types of pavement components.
