cold crushing strength load rate of concrete

Determination of appropriate mix ratios for concrete

Concrete grades or strength classes are specified in terms of the minimum 150 mm diameter by 300 mm compressive cylinder strength and the minimum 150 mm cube compressive strength. Concrete grades or strength classes denotes the compressive strength of concrete which is taken as the 28 days crushing strength of concrete cubes or cylinders .

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.
