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.

2021-2-8 Compressive strength is measured in psi (pounds per square inch). The higher the psi the stronger, and consequently more expensive the concrete is. The minimum psi required depends on the project, however, in general, the bare psi level for any concrete project begins at around 2,500 psi.
