Which shall fall between 7.5 to 12.5 % If not a repeat shall be made with adjusted load to bring the fines within the range of 7.5 to 15.0 percent. The mean percentage fines from the two tests (say Y %) at this load shall be used in the formula to calculate the load required to give 10% fines: Y+4

Get PriceEmail contactAggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.

Get PriceEmail contact2.16 The aggregate crushing value is the ratio of the mass of fines formed by the crushing process to the total mass of the sample expressed as a percentage. Percentage fines = B/A x 100 (to the first decimal place) where . A = The mass of the surface dry sample. B =The mass of the fraction passing the 2.36mm sieve after crushing. 2.17 The mean result of the two tests will be reported to the ...

Get PriceEmail contactAggregate crushing value test provides the resistance of an aggregate sample to crushing under gradually applied compressive load. Generally, the test is conducted on aggregate passing 12.5 mm and retained on 10 mm sieve. The aggregate sample is filled in a cylindrical mold and a load of 40 ton is applied through a plunger in a compression testing machine.

Get PriceEmail contactTen 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%). This test is very similar to Aggregate ...
