the aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. crushing value is a measure of the strength of the aggregate. the aggregates should therefore have minimum crushing value. apparatusmar 28, 2021 aggregate crushing test :1963 & BS :1990) 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 under gradually applied compressive loads.calculate aggregate crushing value. 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 100. where, is weight of surface-dry sample
oct 04, 2020 aggregate crushing value test aim: To find aggregate crushing value of the given aggregate sample. apparatus: steel cylinder, cylindrical measure, steel temping rod, balance, compressions testing machine procedure: the aggregate passing 12.5 mm sieve and retained on mm IS sieve ishow to determine aggregate crushing value civil delights the apparatus of the aggregate crushing value test as per is: 2386 1963 consists of: diameter open ended steel cylinder with plunger and base plate, of the general form and dimensions as shown in figthe aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing apply a gradually increasing compressive load. the strength of aggregate is calculated by the crushing value test. procedure collect aggregate passing from 12.5 mm and retained in mm i.s. sieve. weigh about 6.5 kg of aggregate obtain
aggregate crushing value test step by step procedure the average crushing value in the different tests is the actual crushing value of aggregate important points to remember It is recommended that the crushing value of aggregate should be less than 30% If it is more than then 10% finer aggregate is suggested to use the aggregate whose crushing value is less than 30% can be used may 08, 2013 aggregate crushing value test appratus; preparation of sample. test sample consist of aggregate passing a 12.m IS sieve and retained on a IS sieve. the aggregate to be tested is dried in oven for a period of not less than hours. procedureaggregate crushing value test step by step procedure. aggregate crushing value can be determined by using a simple formula: this test is repeated once or twice and the average crushing value of the aggregate is determined.the average crushing value in the different tests is the actual crushing value of aggregate.
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 or higher, 4.procedure 1.the material for the standard test shall consist of aggregate mar 29, 2021 aggregate crushing test :1963 & BS :1990) 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 under gradually applied compressive loads.impact and crushing value aggregate crushing value sets. uta-0630 aggregate crushing value set 150 mm bs. uta-0640 aggregate crushing value set mm bs. the aggregate crushing value test set measures how resistant an aggregate is, when being crushed under a gradually applied compressive load.
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.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. all parts of the apparatus are powder coated or galvanized steel, heat treated and ground aggregate crushing value test procedure and result. for the aggregate crushing value test an aggregate sample passing through 125 mm IS sieve and retained on IS sieve is selected and dried to a temperature of 105 to 110 then cooled to room temperature. learn more
