Properties of concrete - Wikipedia

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 [15].
