Read Moreactual crushing value of aggregate Important points to remember 1It is recommended that the crushing value of aggregate should be less than 30 If it is more than 30 then 10 finer aggregate is suggested to use 2The aggregate whose crushing value is less than 30 can be used for cement concrete road 3The aggregate whose crushing value is less than 40 can be used for wearing surface
Read MoreThe average crushing value in the different tests is the actual crushing value of aggregate Important points to remember It is recommended that the crushing value of aggregate should be less than 30 If it is more than 30 then 10 finer aggregate is suggested to use The aggregate whose crushing value is less than 30 can be used for cement concrete road The aggregate whose crushing value is less
Read MoreTheory The aggregate crushing value give a relative measure of the resistance of an aggregate to crushing under gradually applied compressive load Its the percentage by weight of the crushedfiner material obtained when the test aggregates are subjected to a specified load under standardized conditions and is a numerical index of the strength of the aggregate used in road construction
Read MoreAggregate 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

Read MoreAggregate Crushing Value ACV and Ten Percent Fines Value TFV These tests are a measure of the crushing properties of aggregate and use the same basic equipment The ACV test requires a standard load of 400 kN to be applied over a period of 10 minutes while the TFV test measures the force required to produce a specified depth of plunger penetration
Read Moreused for concreteothet than for wearing surfaces the aggregate crushing value shall not exceed 45 percent according to the ISS However aggregate crushing values have not been specified by the IRC for coarse aggregates to be used in bituminous pavement construction methods 1

Read MoreOne of the requirements for the suitability of aggregates for construction is the ability of the aggregate to resist crushing The Aggregate Crushing Value gives a relative measure of the resistance of the aggregate to crushing under a gradually applied compressive load 7712 Scope
Read MoreAggregate Crushing value is a measure of the strength of the aggregate The strength of concrete largely depends upon the strength of aggregate The aggregate should therefore have minimum crushing value The aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under gradually applied crushing load
Read MoreAggregate Crushing value depends on the shape of agg also Angular aggregates have a lower ACV than Irregular or rounded aggregatesIf we cut a core out of the same agg Say in the quarry and test for compressive strength will give a higher MPa value It can be considered as a concrete cylinder or UCS tested in lab So it is hard to corelate
Read MoreCalculation of aggregate crushing value The aggregate crushing value is defined as the ratio of the weight of fines passing through specified IS here 236mm sieve to the total weight of sample expressed in percentage W1 Weigh of the total aggregates WaWe W2 Weigh of aggregates passing through 236mm IS sieve Aggregate crushing value W2 W1 100
