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.

Coarse aggregate is used to describe particles larger than 4.75 mm, and the term fine aggregate is used for particles smaller than 4.75mm. Fine aggregates contain particles in the size range 75 µm to 4.75 mm, and coarse aggregates from 4.75 to about 40 mm, except for mass concrete which may contain particles up to 150 mm.

Grade of concrete is defined by the strength and composition of the concrete.It is also defined as the minimum crushing strength of 150mm concrete cube after 28 days of curing.It is denoted by prefixing M to desired strength in MPa. For example, if there is a concrete mix with compressive strength of 15MPa, then its grade will be represented by M15.
