Concept and significance of the Aggregate crushing value test The ‘ aggregate crushing value test ` gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load under.Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load 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 (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 1 It is recommended that the crushing value of.Sampling for Aggregate Crushing Value Test For the Aggregate crushing value test an aggregate sample passing through 12 5 mm IS sieve and retained on 10mm IS sieve is selected and dried to a temperature of 105 C to 110 C then cooled to room temperature
Calculate Aggregate Crushing Value The ratio of the weight of fines formed to the total sample weight in each test shall be expressed as a percentage the result being recorded to the first decimal place Aggregate Crushing Value = W B W A 100 Where W A is weight of surface dry sample.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 kinds of loads that the aggregates will be subjected to during their service life
The aggregate crushing value test result should not be than 30 for the concrete used for roads and pavements and in case of other structures it may be permitted up to 45 (c) Standard Guidelines for Crushing Test Followings are the standard guidelines for the crushing test on aggregates.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 value is higher when percentage of aggregates crush and break into smaller pieces which indicates the aggregates are of a lower quality 2 Aggregate crushing value 45 for aggregates used for concrete for non wearing surfaces and 25 for wearing surfaces like.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 – 12 5mm 10mm and 2 36mm Procedure to determine Aggregate Crushing Value
With aggregate of aggregate impact value higher than 30 the result may be anomalous Also aggregate sizes ‘larger than 14 mm are not appropriate to the aggregate impact test The standard aggregate impact test shall be made on aggregate passing a 14 0 mm BS test sieve and retained on a10 0 mm BS test sieve.Significance of Aggregate Crushing Value Test The crushing value test is conducted on aggregates that are used for the construction of roads Lower crushing value aggregates give much durability for roads due to its lower crushed fraction under the compression load The road is subjected to motion pressure continuously
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 14 0 mm test sieve and retained on a 10 0 mm test sieve For other size fractions there is another recommended method.Crushing resistance of coarse aggregate is the key to the stability and durability of the skeleton structure of permeable asphalt (PA) mixture To determine the technical requirements of crushing value of coarse aggregate used in PA mixture step loading compression tests were conducted on the mixtures of PA 13 and a control asphalt mixture AC 13 respectively
