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.

The impact value of aggregates was determined by following the TS-EN 1097–2 test standard. A high impact value indicates that the aggregate is low resistance to fragmentation. It is evaluated that materials with an impact value above 35 are very weak, those between 10 and 35 are acceptable, and those below 10 are highly durable [33].
