[19,20,21,22,23] Kwek and Awang (2018) [19] Water The aggregate impact value test determines the aggregate's resistance to sudden loading [24], which may differ from the resistance to .
Scope: This Part of BS 812 describes methods for the determination of the aggregate impact value (AIV) which gives a relative measure of the resistance of an aggregate to sudden shock or impact. Principle A test specimen is compacted, in a Concept: Aggregate Impact Test: It is conducted to determine the toughness of the aggregates. For testing, the specimen passing through 12.5 mm sieve but retained on 10 mm sieve is filled in 3 layers with 25 time stamping on each layer and then hammer of 13.5 to 14 kg is dropped freely from a height of 38 cm for 15 blows.. Aggregate impact value is then the . Procedure of Impact Test. The procedure of the impact value test includes the following series of steps: 1. The aggregate samples of size 10mm to 12.5mm (passing through 12.5mm sieve and retained on 10mm sieve) are first taken and oven-dried at a temperature ranging from 100 degrees Celsius to 110 degrees Celsius for about four hours.Aggregate Impact Value; Test Specifications: Aggregate Impact Value.
