    Objective Of Aggregate Crushing Value Test

    AGGREGATE CRUSHING VALUE 1.Objective The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggregate of aggregate crushing value 30 or higher, the result may be anomalous, and in such cases the ten percent fines value should be determined instead.As per IS 456, the individual compressive value of a concrete cube should not be less than 75 of its grade. Example – If the concrete grade is M20, then the individual crushing value should not be less than 15 N Sqmm. The individual crushing value difference between the cube should not be.

  • Objective For Aggregate Crushing Value Test

    Objective For Aggregate Crushing Value Test

    The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. For achieving a high quality of pavement, aggregate of higher crushing strength i.e. low crushing value should be preferred. Lower crushing value means higher strength as it indicates a lower crushed fraction under load.Purpose of this Test. The specimen will break at maximum load (1 Division = 5 KN), which is noted down as the crushing value of the cube. The average (Minimum Three Sample) crushing value should be note down as the compression value of the selected concrete batch. Video Courtesy – NCTEL.
