jan 13, 2011 aggregate crushing value. this test helps to determine the aggregate crushing value of coarse aggregates as per is: 2386 1963. the apparatus used is cylindrical measure and plunger, compression testing machine, IS sieves of sizes 12.m, and 2.m.may 08, 2013 calculation. the ratio of the weight of fines formed to the total sample weight in each test is to be expressed as a percentage, to the first decimal 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. the crushing value of aggregate 100. lab report

jan 13, 2011 aggregate crushing value depends on the shape of agg also. angular aggregates have a lower acv, than irregular or rounded aggregates.if we cut a core out of the same agg and test for compressive strength, will give a higher mpa value. It can be considered as a concrete cylinder or ucs tested in lab. So it is hard to corelateoct 03, 2019 aggregate crushing value is determined by taking a percentage of weight crushed aggregate sample passing through 2.36 mm IS sieve divided by weight of aggregate sample taken for test aggregate crushing value formula is given below, aggregate crushing value or empty weight of cylindrical measure.aggregate crushing value 100 100. where, is weight of surface-dry sample. is weight of fraction passing the appropriate sieve. reporting of results. the mean of the two results shall be reported to the nearest whole number as the aggregate crushing value of

jan 27, 2019 the crushing value of aggregate is very important to know the strength of the aggregate. for finding the resistance of aggregate under gradually applied compressive load, the crushing value test of aggregate is done. for the crushing value crushing value of aggregate. is total weight of sample, is weight of sample passing 2.m sieve, is weight of sample retained on 2.m sieve, then aggregate crushing value is. 100 100 100 100.
