specification: 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 partsthe 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 fig straight metal tamping rod the crushing value test of aggregate provides the resistance of an aggregate sample to crushing under gradually applied compressive load.generally, the test is conducted on aggregate passing 12.5 mm and retained on a mm sieve.the aggregate sample is filled in a cylindrical mold and a load of tons is applied through a plunger in a compression testing machine.aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. ten percent fines value used for testing aggregate smaller than mm. comprises: 150 mm or diameter steel
function of aggregate crushing value weareivar.nl. function of aggregate crushing value rndiit. the aggregate crushing value of an aggregate is the mass of material, expressed as a percentage of the test sample which 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 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.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 results to the nearest whole number and report the median as the aggregate crushing value. data sheet is given as form 7.7.1.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
Is specification Of aggregate crushing value In Dr congo. aggregate crushing value of coarse aggregate. note the aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. with aggre gate of aggregate crushing value or higher, the result may be anomalous, and inbetween aggregate crushing value and ten percent fines aggregate crushing value for some aggregates in nigeria. such a mathematical relationship, usually established through regression modelling on data collected, is useful in saving time and money cost on site through estimating one variable when another is known.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 may 27, 2020 the crushing value of an aggregate indicates its resistance against crushing under gradually applied compressive loads. the standard aggregate crushing test is made on aggregate passing 12.m IS sieve and retained on mm IS sieve. procedure. about 6.5 Kg material consisting of aggregates passing 12.m IS sieve and retained on sieve is
may 22, 2020 the aggregate crushing value where, is weight of fraction passing 2.m sieve is weight of surface dry sample taken in mould. note. the aggregate crushing value should not be more than 45% for aggregate used for concrete other than the wearing surfaces. 30% for concrete used the surfaces such as runway, roads and air field aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements specifications for aggregate crushing value aggregate crushing value specifications postcatcheraggregate crushing value this test helps to determine the aggregate crushing value of coarse aggregates as per is aggregate crushing value test apparatus is used for measuring resistance of an aggregate to crushing. made of mild steel comprising of: cylindrical cell, internal dia 130 to height, plunger, dia 100 to height, base plate, 200 to square thickness, tamping rod, dia 450 to length.maximum crushing value of good quality of aggregate products. As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any size-reduction requirements including, maximum crushing value of good quality of aggregate, quarry, aggregate, and different kinds of minerals.

specification: 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 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.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.As per is: 383 this apparatus is used to measures resistance of an aggregate to crushing under a gradually applied compressive load. specification: consists of m.s.cylindrical container 150 mm 0.m dia to high with base plate 200 to 230 mm.sqr thick.a plinger of 0.m dia 100 to high.
and, in chinese technical specifications of asphalt pavement construction, the criterion for crushing value of coarse aggregate in PA mixture is the same as that in AC mixtures, no greater than 26%. so, the state of contact stress between coarse aggregates in pa-13 procedure to determine aggregate crushing value the aggregates passing through 12.m and retained on IS sieve are oven-dried at a temperature of 100 to 110 for to rs. ii) the cylinder of the apparatus is filled in layers, each layer tamped with strokes of a tamping rod.
