The capacity of concrete is reported in psi – pounds per sq. inch in US units and in MPa – mega pascals in SI units.This is usually called as the characteristic compressive strength of concrete fc/ fck. For normal field applications, the concrete strength can vary from 10Mpa to 60 Mpa.

As a thumb rule, the minimum compressive strength of a cement mortar must achieve 2/3rd (66%) of its mix design strength after 7 days. In case it does not achieve the minimum 2/3rd strength of the mix design after 7 days, one can conclude the concrete has failed and hence will not achieve the required strength as designed.

Properties of concrete - Wikipedia

In very high-strength concrete mixtures (greater than 70 MPa) the crushing strength of the aggregate can be a limiting factor to the ultimate compressive strength. In lean concretes (with a high water-cement ratio) the crushing strength of the aggregates is not so significant.
