Aggregate crushing value test | Step by Step Procedure

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 cement concrete road. The aggregate whose crushing value is less than 40% can be used for wearing surface.

Aggregate Crushing Value Test - Significance & Test

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.

Aggregate Crushing Value Test Determine Aggregate

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 standardized conditions, and the strength of the aggregate used in road

Aggregate Crushing Value Test - Procedure And Result

Aggregate crushing value is determined by taking a percentage of weight crushed aggregate sample passing through 2.36 mm IS Sieve divided by weight of aggregate sample taken for test Aggregate crushing value = (W3 / W) or W3 / (W2 W1)

What is the Crushing value of Aggregates..?? - Firstalert.in

May 27, 2020· The fraction passing the sieve is weighed (B), aggregate Crushing value= ( B/A)*100. Where B is Termed as the weight of fraction passing 2.36 mm IS sieve. A is Termed as the weight of surface dried sample taken in a mold.

Aggregate Crushing Value Test - L & T - Learning Technology

The material for the standard test consists of aggregates of size 10 mm to 12.5 mm. The aggregates should be in surface dry condition before testing. The aggregates may be dried by heating at 100 degree to 110 degree Celsius for more than 4 hours and cooled to room temperature before testing, if necessary.

Aggregate Crushing Value Test -Determine Aggregate

Calculation of Aggregate Crushing Value. 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 - Procedure And Result. Sampling for Aggregate Crushing Value Test: For the Aggregate crushing value test, an aggregate sample passing through 12.5 mm IS sieve and retained on 10mm IS sieve is selected and dried to a temperature of 105 ºC to 110 ºC then cooled to room temperature.

Aggregate Crushing Value Test - Significance & Test

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.
