Aggregate Crushing values is a relative resistance of aggregates to crushing under gradually applied compressive load In situations when aggregate value 30 or higher the result may be a mistake and in such cases the ten percent fines value should be determined and used instead aggregate crushing value result interpretation
The aggregate crushing value is a numerical index of the resistance of an aggregate to crushing under a gradually applied compressive load It is expressed as the percentage by mass of the crushed or finer material obtained when the test sample is subjected to a specified load under standard conditions
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 Support aggregate crushing machine as per i s 2386 part 4 1963
