Jan 13 2011 Aggregate Crushing Value AGGREGATE CRUSHING VALUE This test helps to determine the aggregate crushing value of coarse aggregates as per IS 2386 Part IV 1963 The apparatus used is Cylindrical measure and plunger Compression testing machine IS Sieves of sizes 125mm 10mm and 236mm Procedure to determine Aggregate Crushing Value
Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements 7 33
Aggregate Crushing Value ACV can be determined by using a simple formula This test is repeated once or twice and the average crushing value of the aggregate is determined The average crushing value in the different tests is the actual crushing value of aggregate Important points to remember 1It is recommended that the crushing value of
the aggregate crushing value ACV which gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load The method is applicable to aggregates passing a 140 mm test sieve and retained on a 100 mm test sieve For other size fractions there is another recommended method
