Experiment No. 4: Determination of the aggregate impact value of different coarse aggregate samples. (BS 812) Scope & significance: Aggregate Impact Value The aggregate impact value gives a relative measure of the toughness or the resistance of aggregate sudden shock or impact is not proportional to the resistance to a slowly applied compressive load.
The aggregates must thus have adequate rigidity to resist their breakdown due to excessive impact. This property is calculated by impact value test. The aggregate impact value is a calculation of the resistance to abrupt impact, bang or shock, which may vary from its resistance to steadily, applied compressive weight. Procedure:
