**Summary：**

the ten percent fines value aggregate discussionTen 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] .

Aggregate Crushing Value Acv And Ten Percent Fines Value Tfv. 2.21 The percentage fines from these two tests at the maximum load will be used in the following formula to calculate the load required to produce 10% fines. Force required to produce 10% fines = 14 x X y + 4 where X and y are as above. 3. Reporting of Results

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.

Aggregate crushing value and ten percent fines value 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 tampingBS ISO :2019 - Aggregates for concrete. Test 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.

Pyrite Testing explained - IGIExample – Ten Percent Fines Value December 5, 2013 29 . Physical Tests - Crushing Ten Per Cent Fines Value (TFV) Test Measure of resistance to crushing BS : 1990 Testing aggregates - Methods for determination of ten per cent fines value (TFV)

ten percent fines aggregate crushing valueWhat is the significance of ten percent fines value in . 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
