  • Aggregate crushing value test | Step by Step Procedure

    The 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 forThe aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load Crushing value is a measure of the strength of the aggregate The aggregates should therefore have minimum crushing value 3 APPARATUS The apparatus of the aggregate crushing value test as per IS: 2386 (Part IV) – 1963 consists of: 1) ADETERMINATION OF AGGREGATE CRUSHING VALUEAggregate Crushing Value Test Determine AggregateConcept and significance of the Aggregate crushing value test The ‘ aggregate crushing value test ` gives a re 27 Division, mirpur12, pallbi : [ protected] Careers; Help Desk; Login; 24/7 Phone Services 555 666 99 00 Add to Cart (Item: 02) Home; Products; About; solotion; Contact; Get A Quotedetails of crushing value of aggregate with practical
