    01032016· 01032016· The results indicate a slightly higher value of k for the more elastic rock Apparently the tougher rock breaks in such a manner as to produce less fine material, so that displacement space is less closely packed with the crushed productAggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load 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 conditionsAggregate Crushing Value Test Determine AggregateE Köken et al, New testing methodology for the quantification of rock crushability: Compressive crushing value (CCV) 1229 Since the crushability of rocks is affected by the rockNew testing methodology for the quantification of rock

  • Rock Crushing Theory and Formula using Kick & Rittinger's Law

    11032016· Rittinger’s theory and law of the energy expended in crushing of rock is that the work of crushing is proportional to the reduction in diameter; or, as I have more fully expressed it: “The work done in crushing is proportional to the surface exposed by the operation; or, better expressed for this purpose, the work done on a given mass of rockE Köken et al, New testing methodology for the quantification of rock crushability: Compressive crushing value (CCV) 1229 Since the crushability of rocks is affected by the rockNew testing methodology for the quantification of rockAGGREGATE 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 Procedure to determine Aggregate Crushing Value i) The aggregates passing through 125mm []Aggregate Crushing Value Civil Engineering Portal
