The crushed aggregate sample which is finer than 2.36 mm is separated and expressed as a percentage of the original weight taken in the mould. The percentage of weight passed through the 2.36m IS sieve is known as Aggregate crushing value.. In situations, when the aggregate value 30 or higher the result may be a mistake and in such cases, the ten percent fines value should be determined ...

May 13, 2018 Determination of ten percent fine. THE DETERMINATION OF THE 10 PER CENT FINES AGGREGATE CRUSHING VALUE 1 SCOPE The 10 per cent Fines Aggregate Crushing Value (10 % FACT) as defined hereunder is determined by measuring the load required to crush a prepared aggregate sample to give 10 per cent material passing a specified sieve after crushing.
determined by measuring the load required to crush a prepared aggregate sample to give 10 per cent material passing a specified sieve after crushing. The procedure described in SABS Method 842 is followed. Definition The 10 per cent Fines Aggregate Crushing Value is the force in kN required to crush a sample of -13,29,5mm aggregate so that 10 per cent of the total test sample will pass a 2, 36 mm sieve. 2 APPARATUS
Aggregate Crushing Value (ACV) and Ten Percent Fines Value (TFV) These tests are a measure of the crushing properties of aggregate and use the same basic equipment. The ACV test requires a standard load of 400 kN to be applied over a period of 10 minutes while the TFV test measures the force required to produce a specified depth of plunger penetration.
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 (W2 x 100) / (W1-W) W2 Weight of fraction passing through the appropriate sieve W1-W Weight of surface dry sample.
The test aims at looking for the forces required to produce 10% of fine values (i.e. weight of fines aggregates/weight of all aggregates 10%). This test is very similar to Aggregate Crushing Test in which a standard force 400kN is applied and fines material expressed as a percentage of the original mass is the aggregate crushing value. Granular sub-base is subjected to repeated loadings from truck types. The
Oct 03, 2019 The percentage of weight passed through the 2.36m IS sieve is known as Aggregate crushing value. In situations, when the aggregate value 30 or higher the result may be a mistake and in such cases, the ten percent fines value should be determined and used instead.

The aggregate crushing value (ACV) 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 compressive load of 400 kN. 2 APPARATUS 2.1 An open-ended steel cylinder of 150 mm nominal diameter with plunger and

Ten percent fines value is a measure of the resistance of aggregate crushing subjected to loading and it is applicable to both weak and strong aggregate. Fine aggregates are defined as those passing 2.36mm sieve. The test aims at looking for the forces required to produce 10% of fine values (i.e. weight of fines aggregates/weight
Ten percent fines value is defined as the load taken by the soaked sample at ten percent of fines. Standard Compression Testing Machine. A cylindrical metal measure having an internal diameter of 57 1 mm and an internal depth of 90 1mm. Steel cylinder open ended with plunger and base plate with a normal internal diameter of 75mm.
