Jun 08, 2019· The crushing strength or aggregate crushing value of a given road aggregate is found out as per IS-2386 Part- 4 The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load To achieve a high quality of pavement aggregate possessing low aggregate crushing value should be preferred
reading of crushing value of aggregate - ecole-ethe Aggregate Crushing Value Test by abhishek kumar - The Aggregate Crushing Value offers a related measure of the resistance of an average to crushing under a compressive load that is gradually applied | is a digital publishing platform that makes it simple to publish magazines
AGGREGATE CRUSHING VALUE This test helps to determine the aggregate crushing value of coarse aggregates as per IS: 2386 (Part IV) – 1963 The apparatus used is Cylindrical measure and plunger, Compression testing machine, IS Sieves of sizes – 125mm, 10mm and 236mm
(DOC) Aggregate crushing value Test Lab Report | Adnan ,
The value is higher when more percentage of aggregates crush and break into smaller pieces which indicates the aggregates are of a lower quality 2 Aggregate crushing value < 45% for aggregates used for concrete for non-wearing surfaces and
How to determine the crushing value of aggregate? - Learn ,
Jan 27, 2019· The aggregate crushing value= B/A*100 Where, B is weight of fraction passing 236mm sieve A is weight of surface dry sample taken in mould; Note The aggregate crushing value should not be more than 45% for aggregate used for concrete other then the wearing surfac
Aggregate Crushing Value Test – Determine Aggregate ,
Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions Aggregate crushing value is a numerical index of the strength of the aggregate and it ,
How to Find Aggregate Crushing Value and Its Test Procedure?
The aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under gradually applied crushing load The aggregate crushing value test is a useful guide when dealing with aggregates of unknown performance, particularly when lower strength is suspected
The 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 21 An .
