Concept: Aggregate Impact Test: It is conducted to determine the toughness of the aggregates. For testing, the specimen passing through mm sieve but retained on 10 mm sieve is filled in 3 layers with 25 time stamping on each layer and then hammer of to 14 kg is dropped freely from a height of 38 cm for 15 blows. Aggregate impact value is then the percentage of fine passing through 2 ...

The aggregates should therefore have sufficient toughness to resist their disintegration due to impact. This characteristic is measured by impact value test. 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. Features: A heavy base with two vertical guides fitted with a cross bar at the ...
