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 of all aggregates = 10%).
The mean of the crushing value obtained in the two tetsis reported as the aggregate crushing value Determination of Ten Percent Fines Value The ten percent fines value is a measure of resistance of tbe aggregates to the crushing The apparatusand materials used are the same as for tbe standard aggregate crushing test.

such cases the 'ten percent fines value' should be determined instead. NOTE 2 - The standard aggregate crushing test shall be made on aggre a 12.5-mm IS Sieve and retained on a IO-mm IS Sieve.
Aggregate 'Ten Percent Fine Value' (TPFV): The other way of representing the strength of aggregate is the 'ten percent fine value' (TPFV), that is basically the load needed for 10% fines. As compared to aggregate crushing value test this test is more reliable for representing the strength of aggregate.
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
previously used in the UK and Ireland, such as Aggregate Crushing Value, Ten Percent Fines Value, Aggregate Impact Value, and Wet Attrition Value, have been withdrawn from use, and do not now have the status of a national standard. Flakiness Index is now measured using round bar sieves, rather than slotted trays. Sieve sizes have also been

Ten percent fines value: ten percent fines value reflects the strength performance of aggregate. For heavy-duty concrete elements, aggregate is required to have a value of at least 150 kN [22] . For non-structural element and sub-base, the values need to exceed 50 kN [14], [23] .
This British Standard, a Part of the BS 812 series, describes methods for the determination of the ten per cent fines value (TFV) of aggregates which give a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load.

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.
