Welcome to the high-quality mining machines zone!
May 17 2019 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 standardized conditions and the strength of the aggregate used in
The aggregates crushing value test should be performed as per is code 2386 part iv first fill the sample aggregate with onethird of the cylindrical measure in three layers each layer should be tamped 25times freely after filling the sample aggregate weigh and record it as w1
Aggregate crushing value test report result conclusion aggregate crushing value test report result conclusion discussion for aggregate crushing value test discussion for aggregate crushing value test milling is also known as grinding it is a material more refining process a a study on types and quality of aggregates used in chat online
Feb 08 2012 two tests are required and the ten percent fines values tfv are averaged to obtain the final result reported to the nearest 10 kn for forces 100knprocedure aggregate crushing value ss 19741 the apparatus and sample preparation is identical with that described above for the ten percent fines test2
Dec 15 2017 aggregate impact values and aggregate crushing values are often numerically very similar and indicate similar aggregate strength properties classification of aggregates using aggregate impact value is as given below aggregate impact value classification 20 exceptionally strong 10 20 strong 2030 satisfactory for road surfacing 35 weak for road surfacing
Aggregate impact value aggregate impact value ba100 where a weight of oven dried sample aggregate impact value b weight of fraction passing bs sieve no 7 observations results a total wt of the sample b fraction passing bs sieve 7 after crushing aggregate impact value aggregate impact value ba100
Test method is 2386 p1 1963 impact value this test helps in determining the value which indicates the ability of an aggregate to resist crushing the lower the figure the stronger the aggregate ie the greater its ability to resist crushing test method is 2386 p4
The aggregate impact value is a measure of resistance to sudden impact or shock which may differ from its resistance to gradually applied compressive load procedure o f aggregate impact test the test sample consists of aggregates sized 100 mm 125 mm aggregates may be dried by heating at 100110 c for a period of 4 hours and cooled
The results obtained show that acv value for aggregates are 2504 2270 3613and 3789 for crushed granite slag hoggin allin aggregate and river gravel respectively this show that the
Aggregate crushing value w2 x 100 w1w w2 weight of fraction passing through the appropriate sieve w1w weight of surface dry sample the mean of two result to nearest whole number is the aggregate crushing value result the aggregate crushing value of the given sample aggregate crushing values for roads and pavement construction
25001990 acv 100 2500 204 result aggregate crushing value 204 result analysis 1 the value is higher when more 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 nonwearing surfaces and 25 for wearing surfaces like runways and roadways
