Different Grades of Concrete, Their Strength and Selection

What is Grade of Concrete? 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.
