Get Price ListAggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements. Crushing value of aggregates indicates its strength. Lower crushing value is recommended for roads and pavements as it indicates a lower crushed fraction under load and would give a longer service life and a more economical performance.
The percentage of weight passed through 2.36m IS sieve is known as Aggregate crushing value. Aggregate Crushing values is a relative resistance of aggregates to crushing under gradually applied compressive load In situations when aggregate value 30 or higher the result may be a mistake and in such cases the ten percent fines value should be determined and used instead.

Number. Report the mean as the Aggregate Crushing Value unless the individual results differ by more than 0.07 times the mean value. In this case repeat the test on two further specimens calculate the median of the four results to the nearest whole number and report the median as the Aggregate Crushing Value. A data sheet is given as Form 7.7.1.

2.16 The aggregate crushing value is the ratio of the mass of fines formed by the crushing process to the total mass of the sample expressed as a percentage. Percentage fines
To evaluate the toughness of a stone i.e. the resistance of the aggregates to fracture under repeated impacts is called Impact Test.This test is done to determine the aggregate impact value of coarse aggregate as per IS 2386 PartIV 1993. Aggregate Impact Value Test as per IS 2386 Part
Aggregate Crushing Value Test As Per Code. 201821 aggregate crushing value of coarse aggregate. NOTE 2 The standard aggregate crushing test shall be made on aggre a 12.5mm IS Sieve and retained on a IOmm IS Sieve.
SIGNIFICANCE The model developed for the relationship between aggregate crushing value ACV and ten percent fines aggregate crushing test TFV is useful in economics and safety perspective in
7.6.6.2 Calculation and expression of result a Calculate the aggregate impact value AIV expressed as a percentage to the first decimal place for each test specimen from the following expression. AIV 100 x M 2 M 1 Where M1 is the mass of the test specimen in grams. M2 is the mass of the material passing the 2.36mm test sieve in grams.
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. Granular sub
Then crushed aggregates are then sieved through 2.36 mm sieve and weight of passing material is expressed as percentage of the weight of the total sample which is the aggregate crushing value. A value less than 10 signifies an exceptionally strong aggregate while above 35 would normally be regarded as weak aggregates.
Feb 08 2012nbsp018332Aggregate impact and 1. 10 Aggregate Crushing Value TestINTRODUCTION The principal mechanical properties reired in road stones are Q satisfactory resistance to crushingunder the roller during construction and jjI adequate resistance to surface abrasion under traffic.
Various Lab Test On Aggregates Posted in Material Testing Aggregate Crushing Value please told me what is the frequency of testing of fine aggregate and course aggregate as per IS stander specification Reply Link. Michubu Titus September 29 2016 at 1054 am.
Sep 12 2015nbsp018332The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load. The test consists of subjecting the specimen of aggregate in standard mould to a compression test under standard load conditions See Fig
Standard is complied with the final value observed or calculated expressing the result of a test or analysis shall be rounded off in Fine aggregate produced by crushing hard stone. 2.1.3 Crushed Grace1 Sand crushed gravel or stone when it results from crushing of gravel or hard stone and c partially crushed gravel or stone when it
Test on aggregate Any Concrete work before must be Test on aggregate because of sure working quality of Concrete. Difference type of test no aggregates. as per below tests point out of aggregate tests Sampling of Aggregate Tests Aggregate Crushing Value Impact Value of Coarse Aggregate Sieve Analysis Test of Coarse Aggregates Flakiness Index of
Aggregate suitable for use as pipe bedding would display a low compaction fraction indicating it reaches a state of near full compaction under loose placement. Test Method Crushing Value The Aggregate Crushing Value offers a related measure of the resistance of an average to crushing under a compressive load that is gradually applied.
The Aggregate Crushing Value ACV Test Set measures how resistant an aggregate is when being crushed under a gradually applied compressive load. Each set consists of steel cylinder plunger base plate cylindrical measure and tamping rod.
Agregate crushing volue result as per is. To determine the aggregate crushing value of coarse aggregates as per IS 2386.as per require IS code thus it is a suitable to use results in increased consumption of natural aggregate mechanical properties like crushing value Impact.
Jan 23 2018nbsp018332Aggregate having AIV equal or greater than 35 is considered bad to use in road construction. PURPOSE OF TEST Aggregate Impact Value test determines the Aggregate Impact Value AIV of aggregates which provides a relative measure of the resistance of an aggregate to sudden shock or impact. Resistance of the aggregates to impact is termed as
The aggregate crushing value is defined as a ratio of the weight of fines passing the specified IS sieve to the total weight of the sample expressed as a percentage.
Apr 06 2020nbsp018332The crushing strength or aggregate crushing value of a given road aggregate is found out as per IS2386 Part
It is defined as the resistance of aggregate to failure by impact. The impact value of bulk aggregate can be determined as per I.S. 2386 1963. The test procedure is as follows The aggregate shall be taken as in the case of crushing strength value test i.e. the aggregate should pass through 12.5 mm I.S. sieve and retained on 10 mm I.S. sieve.
May 08 2013nbsp018332Aggregate crushing Value W B W A 215 100 Record. The mean of the two results is reported to the nearest whole number as the aggregate crushing value of the tested material. Safety amp Precautions Use hand gloves while removing containers from oven after switching off the oven. To wear safety shoes amp helmet during the time of test.
If the aggregate crushing value is less than 10 it signifies an exceptionally strong aggregate. Whereas if the crushing value is 35 or above it would normally be considered as weak aggregate. After performing the test the crushed material is separated and calculated in terms of percentage of the original weight taken in the mould.
The tests for Aggregate Crushing Value ACV and FACT 10 Fines Aggregate Crushing Test measure the crushing strength of broken rock. These results do not necessarily relate to the exural or compressive strength of concrete made with that aggregate but are a useful index of overall quality. Normal values for ACV range from 14 to 30 and for
Gate 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. NOTE 2 The standard aggregate crushing test shall be made on aggre a 12.5mm IS Sieve and retained on a IO
