Contact2021-12-9 The grade of concrete is the minimum strength that the quality-controlled concrete posses after 28 days of construction. There are different grades of concrete like M15, M20, M25, M60, etc. For small-scale constructions; normal grade concretes like M10, M15M20 are used.

ContactGrade 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.
