BS 882, The British Standard Specification for Aggregates from Natural Sources for Concrete, specified 10 per cent fines values or aggregate impact values based upon the end use of the concrete. Because the Los Angeles value does not correlate with the required properties, the UK National Guidance ( BSI, 2003 ) to 12620, Aggregates for Concrete, recommends a single value for normal concrete

Methods for determination of aggregate impact value (AIV

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. Two procedures are described, one in which the aggregate is tested in a dry condition, and the other in a soaked condition. The methods are applicable to aggregates passing at 14.0 mm test sieve and retained

13/02/2020 Determination of aggregate impact value (AIV) of given aggregate sample (BS-812) Significance: Aggregates used in the construction of roads should be strong enough to resist crushing under traffic wheel loads. It gives relative measure of the resistance of an aggregate to sudden shock or impact. Increase in impact value will indicate reduction in strength of material. Apparatus:
