theory aggregate crushing value - KPJ Langeveen. 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 .
Dec 19 2019 If the aggregate crushing value is less than 10 it signifies an exceptionally strong aggregate. Whereas if the crushing value is 35 or above it would normally be considered as weak aggregate. After performing the test the crushed material is separated and calculated in terms of percentage of the original weight taken in the mould.

The apparatus used is Cylindrical measure and plunger Compression testing machine IS Sieves of sizes 12.5mm 10mm and 2.36mm Procedure to determine Aggregate Crushing Value i The aggregates passing through 12.5mm
Read MoreAggregate Crushing Value ACV 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 slowly applied compressive load. With aggregate of aggregate impact value higher than 30 the result may be anomalous.
Read MoreThe 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 .

Read MoreJun 11 2021 To determine aggregate impact value of given aggregate. THEORY Toughness is the property of a material to resist impact. Due to traffic loads the road stones are subjected to the pounding action or impact and there is possibility of stones breaking into smaller pieces. The road stones should therefore be tough enough to resist fracture under .
