2 days ago aggregate crushing test is 2386part 41963 amp bs 8121101990 aggregate crushing test values indicates the strength of aggregate and hence it is very significant similarly we can say crushing value is the relative measure of resistance of an aggregate under gradually applied compressive loads
The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load crushing value is a measure of the strength of the aggregate the aggregates should therefore have minimum crushing value 3

Calculation 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
May 27 2020 the crushing value of an aggregate indicates its resistance against crushing under gradually applied compressive loads the standard aggregate crushing test is made on aggregate passing 125mm is sieve and retained on 10 mm is sieve procedure about 65 kg material consisting of aggregates passing 125mm is sieve and retained on 10mm sieve is
This important property of aggregate is determined by the aggregate impact value test this resistance of aggregate may differ from resistance to gradual load which we measure in the crushing value test importance of impact value test generally the majority of the aggregate test is carried out to know the response of aggregates to different
Aggregate 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
The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load to achieve a high quality of pavement aggregates possessing low aggregate crushing value should be preferred
