Properties of concrete Wikipedia

In very highstrength 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 watercement ratio) the crushing strength of the aggregates is not so significant.
