Concept and significance of the Aggregate crushing value test. The ‘ aggregate crushing value test ` gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. 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

How to determine the crushing value of aggregate? Civil Tips

May 22, 2020· The aggregate crushing value= B/A*100 . Where, B is weight of fraction passing 2.36mm sieve ; A is weight of surface dry sample taken in mould. Note. The aggregate crushing value should not be more than 45% for aggregate used for concrete other than the wearing surfaces. 30% for concrete used the surfaces such as runway, roads and air field

Aggregate Crushing Value Test Civil Planets

The crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.36mm and the weight of the dried aggregate sample. At least three samples should be tested from the same batch and average value to get accurate results. The crushing value of aggregate = (W2/W1) x 100. Lab Report

Aggregate crushing value test Civil Concept

The average crushing value in the different tests is the actual crushing value of aggregate. Important points to remember. It is recommended that the crushing value of aggregate should be less than 30%. If it is more than 30 % then 10% finer aggregate is suggested to use. The aggregate whose crushing value is less than 30% can be used for

Classification & Test on Aggregate Civil Engineering Notes

This test gives the Aggregates Crushing Value (ACV), which is an index of crushing strength of aggregates. The apparatus used for this test is Compression Testing Machine / Universal Testing Machine. A sample of aggregates in surface dry condition, which pass through the 12.5 mm sieve and are retained on 10 mm sieve are taken for this test (W1).
