Aggregate Impact value Test Apparatus, Procedure and uses
Procedure of Aggregate Impact value test. The test sample: normally aggregates sized 10.0 mm to 12.5 mm. the aggregates should be dried by heating at 100-110 0C for a period of 4 hours and cooled. Sieve the material through 12.5mm and 10.0 mm IS sieves. The aggregates passing through the 12.5 mm sieve comprise the test material.

Ten per cent fines value (TFV) — Material Testing Expert
The 10% fines value is a metric that gauges the ability of aggregates to withstand crushing under loading, and it is applicable to both weak and strong aggregates. Fine aggregates are those that pass through a 2.36mm sieve. This test seeks to determine the amount of force required to produce 10% of fine values, which is expressed as the …
