calculation of aggregate crushing value. the crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.m and the weight of the dried aggregate sample. At least three samples should be tested from the same batch and average value to get accurate results.
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 IS sieve is selected and dried to a temperature of 105 to 110 then cooled to room temperature. To fill the cylindrical measure mould about 6.5 kg of a sample of aggregate is sufficient.
aggregate impact value this test is done to determine the aggregate impact value of coarse aggregates as per IS 2386 part IV 1963. conclusion aggregate impact value test kefid mining milling is also known as grinding, it is a material more refining process.
discussions and conclusions. the values of aggregate crushing test agree in general with that of aggregate impact test. the crushing strength test is most significant as far as the conditions to which the aggregates is likely to be subjected in practice are concerned. the suitability of aggregate in the pavement layers is dependent upon the
1.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 BA 100 where weight of oven-dried sample weight in of fraction passing through 2.36 mm IS sieve. 6.video aggregate crushing value test

It is recommended that the crushing value of aggregate should be less than 30. If it is more than then finer aggregate is suggested to use. the aggregate whose crushing value is less than can be used for cement concrete road. the aggregate whose crushing value is less than can be used for wearing surface.
