    7 Lab Test on Aggregate Should Satisfy for Use in Concrete

    The aggregate crushing value test indicates the strength of aggregate which is the most essential property of coarse aggregate. 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.
