1.While we talk about the strength of coarse aggregates it refers to the crushing strength of the aggregate itself However, the required information on strength of coarse aggregates can be obtained from indirect tests: crushing strength of prepared rock samples, crushed value of bulk aggregate, and performance of aggregate in concrete

2.Comp strength concrete < Comp strength aggregate The crushing strength of aggregate cannot be tested with any direct test There are some indirect tests to inform us about thecombining of fine and coarse aggregates so as to produce desired grading See Table 45, 46
