### Different Grades of Concrete, Their Strength and Selection ...

Grade of concrete is defined as the minimum strength the concrete must posses after 28 days of construction with proper quality control. Grade of concrete is denoted by prefixing M to the desired strength in MPa. For example, for a grade of concrete with 20 MPa strength, it will be denoted by M20, where M stands for Mix.

### Day Compressive Strength - an overview | ScienceDirect Topics

The 28 days compressive strength of concrete is usually obtained from cylinders with a height to diameter ratio of 2 (such as a standard 150 mm diameter by 300 mm high cylinder) loaded longitudinally to failure. In addition to the cylinder specimen, the cube specimens are also used for concrete test.
