PDF DETERMINATION OF AGGREGATE IMPACT VALUE AIV BS 812 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
Exp 4 Aggregate Impact Value - Civil Engineers PKExperiment No. 4: Determination of the aggregate impact value of different coarse aggregate samples. BS 812 Scope and 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.
Aggregate Impact - an overview ScienceDirect Topics188.8.131.52 Aggregate Impact Value and Impact Value. The relative measurement of aggregate resistance to sudden impact is detailed in BS 812-112:1990. The old British Standards method is still used by some UK laboratories as it is confirmed as ‘current’ by BSI.
Determination of Aggregate Impact Value - Impact Test on The aggregate impact value is a measure of resistance to sudden impact or shock, which may differ from its resistance to gradually applied compressive load. Procedure o f Aggregate Impact Test The test sample consists of aggregates sized 10.0 mm 12.5 mm. Aggregates may be dried by heating at 100-110 C for a period of 4 hours and cooled.
Aggregate Impact Value Testing AIV TEST Civil Engineering The aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, which in some aggregates differs from Its resistance to a slow compression load. The Indian Standard CODE IS 2386 Part IV – 1963 is used for procedure and classifi ion of aggregate by result.
