Mar 29 2021 aggregate crushing test is 2386part 41963 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
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 aggregate crushing value w2 w1 100
Aggregate crushing value w1w2100 recommended values in aggregate crushing test if aggregate crushing value is less than 10 it signifies an exceptionally strong aggregate
May 22 2020 calculation process the aggregate crushing value ba100 where b is weight of fraction passing 236mm sieve a is weight of surface dry sample taken in mould note the aggregate crushing value should not be more than 45 for aggregate used
Aggregate crushing value is determined by taking a percentage of weight crushed aggregate sample passing through 236 mm is sieve divided by weight of aggregate sample taken for test aggregate crushing value formula is given below aggregate crushing value w3 w or w3 w2 w1 w1 empty weight of cylindrical measure w2 weight of aggregate with cylindrical measure
To calculate aggregate crushing value by testing aggregate passing 125 mm sieve and retained on a 10 mm sieve
Calculationaggregate impact value is the ratio of the weight of the fraction passing through 236 mm weight w2 by the total weight of the sample weight w1 w2 aggregate impact value w2 w1w2 100 80 gm 300 gm 2667 impact value where w1 weight of the fraction passing through 236 mm is sieve220 gm
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 determined instead
7718 calculation and expression of result calculate the aggregate crushing value acv expressed as a percentage to the first decimal place of the mass of fines formed to the total mass of the test specimen from the following expression acv 100 x m 2 m 1 where m 1
Abrasion value calculation abrasion value w1w2w1 x 100 w1 weight of dried aggregate sample w2 weight of aggregate sieved through the is 170mm
To calculate the flakiness index of the given sample of aggregates the weight of each fraction of aggregates passing and retaining on the specified set of sieves is noted first the pieces of aggregates are made to pass through the slot of specified thickness of gauge and then they are weighed

Feb 08 2012 the material passing 236 mm is weighed mass b and expressed as a percentage of the original mass mass a to give the aggregate crushing value acv b acv 100
7718 calculation and expression of result calculate the aggregate crushing value acv expressed as a percentage to the first decimal place of the mass of fines formed to the total mass of the test specimen from the following expression acv 100 x m 2 m 1 where m 1
Dec 19 2014 calculation aggregate crushing value ba x 100 the result should be recorded to the first decimal place and the mean of the two results reported to achieve a high quality of pavement aggregate possessing low crushing value should be preferred 8
May 08 2013 the fines passing 236mmis sieve is weighed and expressed as a percentage of by weight of the test sample calculation the mean percentage fines from the two tests at this load shall be used in the following formula to calculate the load required to give 10 fines load required for 10 fines 14x y 4 x load in tones
Flakiness index w 2 w 1 x 100 where w 2 weight passed from 06 x d mean size w 1 total weight of aggregates flakiness index of aggregates used in road construction should be less than 15 and normally does not exceed 25 relevance and importance
Penetration value of plunger in 10 minutes 150 mm for rounded or partially rounded aggregates 200 mm for normal crushed aggregates 240 mm for honeycombed aggregates result calculation ten percent fines value w2w1 x 100 which shall fall between 75 to 125
