aggregate crushing experiment values We have aggregate crushing experiment values the value is higher when more percentage of aggregates crush and break into smaller pieces which indicates the aggregates are of a lower quality aggregate crushing value for aggregates used for concrete for nonwearing surfaces and for wearing surfaces likechapter standard test procedures tests for aggregates and bricks may 2001 page 7.35 7.7.1.9 results. calculate the mean of the two values determined to the nearest whole 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 investigation of testing methods to determine long ia tech. apr 14, 2005 realizing the importance and also that deficiencies in the from the test results it was found that the wisdot aggregate testing protocol could be 2.1.6 aggregate crushing value (british standard 812
for obtaining representative sample for sieve analysis. It is suitable for dry sands, fine powders, ores, refractory materials, mineral aggregates, pigments, powered coal, soap, cement etc. Up to a maximum particle size of mm. aggregate impact test apparatus with counter. IS 979. aggregate crushing value apparatus IS aggregate crushing value apparatus make: labtek model: sl-ag-001 origin: india standards: IS 2376 & BS 111 specification: the aggregate crushing value test set provides a relative measure of the resistance of an aggregate to crushing under a aggregate crushing value test fines value test mechanical properties of aggregates aggregate crushing value test procedure the material to be tested should pass a 14.0 mm sieve and be retained on a mm sieve. dry the sample
depth to top of test specimen: specdesc grey angular limestone: specimen description: specprep prepared according to client instructions: details of specimen preparation including time between preparation and testing: acvtacv aggregate crushing value: acvtfrac aggregate: size fraction from which test the aggregate crushing value which gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. the method is applicable to aggregates passing a 14.0 mm test sieve and retained on a 10.0 mm test sieve. for other size fractions, there is another recommended method.find here aggregate crushing value apparatus, crushing value apparatus manufacturers, suppliers & exporters in india. get contact details & address of companies manufacturing and supplying aggregate crushing value apparatus, crushing value apparatus across india.
aggregate crushing value apparatus provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. the oven dried and accurately weighed aggregates are subjected to crushing test on compression testing machine and weight of the resultant fines passing the specified IS sieve to the total the aggregate crushing value of an aggregate is the mass of material, expressed as a percentage of the test sample that is crushed finer than a 2.36-mm sieve when a sample of aggregate passing the 13.2-mm and retained on the 9.50-mm sieve is subjected to crushing under a gradually applied compressive load of 400 kn.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
the aggregate crushing value test set provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. each set consists of steel cylinder, plunger, base plate, cylindrical measure and tamping rod.
