Procedure The aggregate sample: The material for the standard test consists of aggregates sized 10.0 mm to 12.5 mm .The aggregates must be in surface dry condition before testing. The aggregates may be dried by heating at 100 oC – 110 o C for not mor than 4 hours and cooled to room temperature before testing, if necessary.

Aggregate Impact Test, Ten Percent Fines Test and Aggregate Crushing Test. BACKGROUND When a road aggregate has been manufactured to a specified grading it is stockpiled, loaded into trucks, transported, tipped, spread and compacted. If the aggregate is weak, some degradation may take place and result in a change in
2020-6-22Crushers Advantages Aggregate Crushing Value Test Advantages aggregate crushing value test report the 10 per cent fines aggregate crushing value is the force in kn required to crush a sample of 13295mm aggregate so that 10 per cent of the total test sample will pass a 2 36 mm sieve astm c131 c131m 14 standard test method for More ...
10 Fines Aggregate Crushing Test. 10 Fines Aggregate Crushing Value Formula 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 aggregate impact and.
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.
Aggregate crushing test is standardized by IS: 2386 part-IV and used to verify the crushing strength of aggregates. The aggregates should be oven dried, which can passes through 12.5mm and retained on 10mm sieve. The cylindrical steel cup is stuffed in three layers of aggregate. Each and every layer is tamped with 25 strokes by the rounded end ...

Jan 10, 2020· For fine aggregate, three different crushers, CC, HSI, and VSI were used and angularity and 2D form of basaltic fine aggregates were investigated . Rajan and Singh reported that the HSI produced the most angular and elongated aggregates. However, they did not study the effect of rock type and recommended that further studies be carried out for ...

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 As in SABS Method 842. 3 METHOD Follow SABS Method.
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 aggregate. After performing the test, the crushed material is separated and calculated in terms of percentage of the original weight taken in the mould.

Number report the mean as the aggregate crushing value unless the individual results differ by more than 007 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 a data sheet is given as form 771
Mar 19, 2020· The test is a rapid, accurate quality control tool to determine the variability of aggregate contamination. With knowledge of concrete mix performance, aggregate clay contamination is an important predictor of concrete behaviour and allows aggregate and concrete producers flexibility for increasing fines utilisation.
