The drum is rotated for a specified number of revolutions. Afterward, the aggregate is removed from the drum and sieved on a No. 12 (1.70 mm) sieve. The aggregate retained on the sieve is weighed and the difference between this weight and the original weight is expressed as a percentage and reported as the L.A. abrasion loss value.
The final reported loss value (reported as a percentage of total aggregate mass) is a weighted average of the mass loss of each size range. Figure 2 shows the sulfate chemical bottles and basket used to suspend the aggregate in the sulfate solution. Figure 2: Aggregate basket surrounded by sulfate bottles. Approximate Test Time. About 5 days.

ten fines value & aggregate crushing value difference 4.7 8164 Ratings ] The Gulin product line, consisting of more than 30 machines, sets the standard for our industry.
These two aggregate samples were tested for sieve analysis test, relative density test, water absorption test, ten percent fine test, aggregate crushing value test (ACV), Aggregate impact value test (AIV), and Abrasion value test. Findings revealed that the best aggregate for road construction is the aggregate from IsiAgu.
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.
10% fines aggregate crushing value (10% FACT), determined in accordance with TMH1 method B2, shall be not less than the appropriate value in table 3602/2, column 3. The Aggregate Crushed Value (ACV), determined in accordance with TMH1 method B1, shall not exceed the appropriate value
7.7 Aggregate Crushing Value and 10% Fines Value 7.7.1 Aggregate Crushing Value (ACV) 7.7.1.1 Introduction. One of the requirements, for the suitability of aggregates for construction, is the ability of the aggregate to resist crushing. The Aggregate Crushing Value gives a relative measure of the resistance of the aggregate to crushing under a
Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.
The crushing test on aggregate gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. If the aggregate crushing value is less than 10, it signifies an exceptionally strong aggregate. Whereas, if the crushing value is 35 or above, it would normally be considered as weak aggregates.
For aggregates smaller than 10 mm, a 75 mm diameter cylinder and associated equipment is available. UTA0630 and UTA0640 Test Sets are also used for the Ten Percent Fines Value (TFV) of aggregates according to BS 812:111. The Aggregate Crushing Value (ACV) Set is supplied complete with: Cylinder, Base Plate, Plunger, Cylindrical Measure
Jul 16, 2014 · Aggregate impact value test gives an indiion of aggregate''s toughness property (i.e. property of a material to resist impact) Aggregate impact values are used to classify the stone aggregates with respect to toughness property as given below. Aggregate impact value (%) Toughness Properties <10 Exceptionally tough / Strong 10 – 20 Very tough / Strong []
Ten Fines Value Amp Aggregate Crushing Value Difference ten fines value & aggregate crushing value difference. ten fines value & aggregate crushing value difference. Mining is the extraction of valuable minerals or other geological materials from the earth, from an orebody, lode, 9.7/10(308) SPECIFIC GRAVITY OF COARSE AGGREGATE AASHTO T 85 .
Experiment No. 4: Determination of the aggregate impact value of different coarse aggregate samples. (BS 812) Scope & significance: Aggregate Impact Value The aggregate impact value gives a relative measure of the toughness or the resistance of aggregate sudden shock or impact is not proportional to the resistance to a slowly applied compressive load.
