AGGREGATE CRUSHING VALUE

AGGREGATE CRUSHING VALUE

AGGREGATE CRUSHING VALUE 1.Objective The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggregate of aggregate crushing value 30 or higher, the result may be anomalous, and in such cases the ten percent fines value should be determined instead. Dec 19, 2019 The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. For achieving a high quality of pavement, aggregate of higher crushing strength i.e. low crushing value should be preferred. Lower crushing value means higher strength as it indicates a lower crushed fraction under load.

Jul 04, 2020 The aggregate crushing value (ACV% W2/W1 x 100). The acceptance criteria for aggregates as in IS 383 specification for crushing test is given below For wearing surfaces the (ACV) value should be lower than or equal to 30 percent. For concrete other than wearing surfaces, the (ACV) value should be lower than or equal to 45 percent. Crushing strength of prepared rock sample, crushing strength of bulk aggregates and the performance of aggregates in concrete can be used to assess the strength of the aggregate. Crushing of prepared rock sample is not used widely. But we should note that a good value of the crushing of a prepared rock sample is 200 Mpa.
