our aggregate crushing valve apparatus is used for measuring of resistance of aggregate to crushing. technical specifications consists of MS cylindrical container 150 mm 0.m diameter to high with base plate 200 to 230 mmsqr thick plunger of 0.m diameter 100 to 115 mm high.
this crushing index test apparatus is used to test the fine aggregate crushing resistance so as to evaluate the aggregate road construction applicability. crushing index apparatus specifications. mold size: i.d depth pressure head dia. metal
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 weight of the sample expressed a a percentage is defined as aggregate crushing value. the apparatus is available in three size dia for to
description and specification for lab tenders. aggregate crushing value apparatus. 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.
crushing resistance of aggregate. the aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under gradually applied crushing load the aggregate crushing value test is a useful guide when dealing with aggregates of unknown performance particularly when lower strength is suspected.
crushing value Of aggregate ppt. introduction on aggregate crushing value apparatus. To achieve a high quality of pavement, aggregate possessing low crushing value should be preferred application: the test can be used to asses the suitability of aggregates with reference to the crushing strength for various type of pavement components the aggregates used for the
calculation of aggregate crushing value. the aggregate crushing value is defined as the ratio of the weight of fines passing through specified IS to the total weight of sample expressed in percentage. weigh of the total aggregates weigh of aggregates passing through 2.m IS sieve. aggregate crushing value 100
calculation of aggregate crushing value. the ratio of weight of fines formed to the weight of total sample in each test shall be expressed as a percentage, the result being recorded to the first decimal place. aggregate crushing value weight of fraction passing through the appropriate sieve. weight of surface dry sample.
aggregate crushing value 1.objective 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, the result may be anomalous, and in such cases the ten percent fines value should be determined instead.
the aggregate crushing value is defined as the ratio of the weight of fines passing through specified IS to the total weight of sample expressed in percentage. weigh of the total aggregates weigh of aggregates passing through 2.m IS sieve. aggregate crushing value 100
the aggregate crushing value is a numerical index of the resistance of an aggregate to crushing under a gradually applied compressive load. It is expressed as the percentage by mass of the crushed material obtained when the test sample is subjected to a
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
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
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 for cement concrete road. the aggregate whose crushing value is less than 40%
