Therefore, 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.
Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load.

The aggregate crushing value is a numerical index of the resistance of an aggregate to crushing under a gradually applied compressive load. It is expressed as the percentage by mass of the crushed (or finer) material obtained when the test sample is subjected to a specified load under standard conditions. Aggregates with lower crushing value indicate a lower crushed fraction under load or
Advantages Of Aggregate Crushing Value Acv Mtm Crusher – aggregate crushing value (12–33 ) and aggregate impact value (10–34 ) – signify that natural aggregates are generally stronger. and shock-resistant than periwinkle shell and cockle.The value is higher when percentage of aggregates crush and break into smaller pieces which indicates the aggregates are of a lower quality.
Impact Value and Crushing Value The recycled concrete aggregate is relatively weaker than the natural aggregate against mechanical actions. As per IS 2386, the impact and crushing value for concrete wearing surfaces should not exceed 50% and 45% respectively.
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 their resistance to a slowly applied compressive load.The property of a material to resist impact is known as toughness.So, the aggregates that are going to be used in construction must have sufficient toughness to resist their disintegration

The ‘ aggregate crushing value test ` gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load under standardized conditions, and the strength of the aggregate used in
The aggregates which may be used in concrete must be free from silt, clay, and other marine impurities. 12. Crushing value of aggregate. Determination of the crushing value of an aggregate is helpful to find the compressive strength of the aggregate, whether it is suitable for the concrete work or not. One of the important properties of
The apparatus of the aggregate impact value test consists of: A testing machine weighing 45 to 60 kg and having a metal base with a plane lower surface of not less than 30 cm in diameter. Level and plane concrete floor of minimum 45 cm thickness are used to support it. The base of the machine should also have provisions for fixing its base.
