crushing strength of aggregate

Strength of Coarse AggregatesWhile 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.
