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
.jpg)
This resistance of aggregate may differ from resistance to gradual load which we measure in the crushing value test importance 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

Note 1 a procedure for testing coarse aggregate larger than 190 mm 3 4 in is covered in test method c535 thus coarse aggregates with a maximum size between 19 mm 3 4 in and 375 mm 1 1 2 in may be tested by test method c535 or test method c131c131m

The test aims at looking for the forces required to produce 10 of fine values ie weight of fines aggregatesweight of all aggregates 10 this test is very similar to aggregate crushing test in which a standard force 400kn is applied and fines material expressed as a percentage of the original mass is the aggregate crushing value

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

An aggregate specimen is compacted into a steel cylinder fitted with a nofriction plunger the specimen is then loaded via the plunger the load crushes the aggregate to an extent depending on the crushing resistance of the material it is measured by a sieving test on the crushed specimen and it is a measure of the aggregate crushing value acv

Sep 12 2015 crushing test fig1 crushing test setup one of the model in which pavement material can fail is by crushing under compressive stress a test is standardized by is 2386 partiv and used to determine the crushing strength of aggregates the aggregate crushing value provides a relative measure of resistance to crushing under gradually applied
Aggregate crushing value of coarse aggregate note 1 the aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load with aggre gate of aggregate crushing value 30 or higher the result may be anomalous and in
Impact and crushing value aggregate crushing value acv sets uta0630 aggregate crushing value acv set 150 mm bs uta0640 aggregate crushing value acv set 75 mm bs the aggregate crushing value acv test set measures how resistant an aggregate is when being crushed under a gradually applied compressive load
The aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under gradually applied crushing load the aggregate crushing value test is a useful guide when dealing with aggregates of unknown performance particularly when lower strength is suspected
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
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 surfacedry sample
Jan 09 2018 aggregate impact value test aiv test is conducted to determine the aggregate impact value of coarse aggregate the aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact which in some aggregates differs from its resistance to a slow compression load
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
