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 10 mm. Comprises 150 mm or 75mm diameter steel cylinder plunger base plate tamping rod and metal measure. More .
Oct 07 2017 For such materials a ten percent fines value test is suggested by BS812 Part 3. Mechanical Properties of Aggregates 10 Fines Value Test BS812 part 3 Procedure In this test the apparatus of the standard crushing test is used to determine the load required to produce 10 fines from the 14.0 to 10.0 mm particles.
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.
Mechanical Properties of Aggregates 10 Fines Value Test BS812 part 3 Procedure In this test the apparatus of the standard crushing test is used to determine the load required to produce 10 fines from the 14.0 to 10.0 mm particles. This is achieved by applying a progressively increasing load on the plunger so as to cause its penetration in 10 minutes of about - 15 mm for rounded .

This method is not suitable for testing aggregates with a crushing value higher than 30 and in this case the ten percent fines value is recommended. 7.7.1.3 Method outline. A test specimen of chosen fractions is compacted in a standardised manner into a steel cylinder fitted with a freely moving plunger.

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.

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 method is not suitable for testing aggregates with an aggregate crushing value higher than 30 and in such cases the method for ten per cent fines value described in BS 812-111 is applicable.
Apr 25 2019 Aggregate 10 Ten percent fines value test procedure of coarse aggregate is required to find out the resistance of coarse aggregate to crushing We described the test procedure of 10 Ten percent fines value of coarse aggregate as per IS code with 10 Ten percent fines value. AGGREGATE CRUSHING VALUE TEST IS 2386
crushing. It is used to determine the crushing value of a given road aggregate also it is used to assess the suitability of aggregate for use in different road pavement. This is not a very effective method in the case of soft aggregates for which the ten percent fines aggregate
Feb 15 2017 Further processing included high rotor speed 70 ms VSI crushing to generate fines and static air-classification of the crusher products into three distinct size fractions with approximately the following d 10 to d 90 ranges 4 m to 25 m fine 20 m to
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 W B W A 100. Where W A is weight of surface-dry sample
Feb 26 2016 The difference between the cumulative percentages at the 3.5 and 1.5 points on the curve gives us the amount of such product to be expected from the output of the primary crusher This is 85 minus 43 or 42 of the primary crusher product. If our problem had covered a crushing condition calling for 80 instead of 85 passing the opening .
Apr 07 2016 In most cases the fine crushing and cubicising functions are combined in a single crushing stage. The selection of a crusher for tertiary crushing calls for both practical experience and theoretical know-how. This is where producers should be sure to call in an experienced applications specialist to make sure a system is properly engineered.

Crushed Stone The Unsung Mineral Hero Crushed stone is often looked upon as one of the lowliest of commodities however it is used for such a wide variety of purposes in so many industries that it should be elevated to a position of distinction. It is the geologic commodity upon which almost everything is built. The Wordle word cloud above shows just a few of its diversity of uses.
