fines 10% test A test that is similar to the aggregate crushing value (ACV) test. A sample of aggregate is subjected to varying loads and the percentage of fines calculated for each load. A graph of loading versus percentage fines is used to find the loading required for 10% fines. Pick a style below, and copy the text for your bibliography.
Apply 10% to 100, and see how each value was calculated. Try 12.5% of 50: the "50 less 12.5%" value is 43.75. Then try 12.5% of 43.75 (shows that before a 12.5% reduction it was 50.) Compare 100 to 110, and see that to go from 100 to 110 is a 10% increase, but to go from 110 back down to 100 is a 9.09% decrease (not a 10% decrease)

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.

If the soil has 5–12% by weight of fines passing a #200 sieve (5% < P #200 < 12%), both grain size distribution and plasticity have a significant effect on the engineering properties of the soil, and dual notation may be used for the group symbol. For example, GW-GM corresponds to "well-graded gravel with silt.". If the soil has more than 15% by weight retained on a #4 sieve (R #4 > 15% ...
Report the mean as the aggregate 10% fines value, unless the individual results differ by more than 10 kN or by more than 0.1 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 10% fines value.

soil has 95 percent fines as opposed to 55 percent fines for the CL-ML soil. In order of increasing permeability, the fine grained USCS classes are: CH CL ME CL-ML ML . 2. Another,group of usually slowly permeable soils are the silty and clayey coarse-grained soils. These soils may have from 13 percent to 49 percent fines.

This document gives the test method for determination of ten percent fines value (TFV) of aggregates. This method gives a relative measure of the resistance of the aggregate crushing under the gradually applied compressive load.
Ten per cent fines load and ACV tests are two well accepted tests for assessing the mechanical properties of aggregates. While the load producing ten per cent fines is determined in the former test, the amount of fines produced under 40 ton load is given as ACV in the latter test. Both tests are standardised in the U.K. and carried out in the same way, on the approximately same amount of ...
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.
