Get PriceMar 30, 2020 The aggregate crushing value test is an important test of aggregates. It gives a numerical index of the strength of the aggregate and it is used for concrete in construction of roads and pavements. The aggregates, have minimum crushing value, are recommended for roads and pavements as it indicates a lower crushed fraction under load and would
Get PriceThe average crushing value in the different tests is the actual crushing value of aggregate. Important points to remember. It is recommended that the crushing value of aggregate should be less than 30%. If it is more than 30 % then 10% finer aggregate is suggested to use. The aggregate whose crushing value is less than 30% can be used for
Get PriceAGGREGATE IMPACT VALUE INTRODUCTION. Aggregates used in road construction, should be strong enough to resist crushing under traffic wheel loads if the aggregates are weak, the stability of the pavement structure is likely to be adversely affected
Get PriceThe aggregate crushing value (ACV) of an aggregate is the mass of material, expressed as a percentage of the test sample. which is crushed finer than a 2,36 mm sieve when a sample of aggregate passing the 13,2 mm and retained on the 9,50 mm sieve is subjected to crushing under a gradually applied compressive load of 400 kN. 2 APPARATUS 2.1 An

Get PriceTherefore, aggregate used for such propose should have sufficient toughness to resist their disintegration due to the impact. This important property of aggregate is determined by the aggregate impact value test. This resistance of aggregate may differ from resistance to gradual load which we measure in the crushing value test
Get PriceThis test is very similar to Aggregate Crushing Test in which a standard force 400kN is applied and fines material expressed as a percentage of the original mass is the aggregate crushing value.
