Aggregate Crushing Value Test Procedure And Result

Calculation of Aggregate Crushing Value: Aggregate crushing value can be found by the following formula, “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)

Aggregate crushing value test Step by Step Procedure

Theaverage crushing valuein the different tests is the actualcrushing valueofaggregate. Important points to remember. It is recommended that thecrushing valueofaggregateshould be less than 30%. If it is more than 30 % then 10% fineraggregateis suggested to use. Theaggregatewhosecrushing valueis less than 30% can be used for cement concrete road. Theaggregatewhosecrushing valueis less …

Aggregate Crushing Value Test L T Learning Technology

Theaggregate crushing valueis a numerical index of the resistance of anaggregatetocrushingunder a gradually applied compressive load. It is expressed as the percentage by mass of thecrushed(or finer) material obtained when the test sample is subjected to a specified load under standard conditions.

Aggregate crushing valueof aggregates with cement

Anaggregatespecimen is compacted into a steel cylinder fitted with a no-friction plunger. The specimen is then loaded via the plunger. The load crushes theaggregateto an extent depending on thecrushingresistance of the material. It is measured by a sieving test on the crushed specimen and it is a measure of theaggregate crushing value(ACV).
