Aggregate Crushing Value Test – Determine Aggregate

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 valueThe aggregates crushing value test should be performed as per IS code 2386 Part IV First, fill the sample aggregate with onethird 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 topAggregate Crushing Value Test Significance & Test2 天前The crushed aggregate sample which is finer than 236 mm is separated and expressed as a percentage of the original weight taken in the mould The percentage of weight passed through the 236m IS sieve is known as Aggregate crushing value In situations, when the aggregate value 30 or higher the result may be a mistake and in such cases, the “ten percent fines value” should be determinedAggregate Crushing Value Test Procedure And Result
