10 Properties of Concrete and their Uses - The Constructor

2016-5-6  Concrete is known by its grade which is designated as M15, M20 etc. in which letter M refers to concrete mix and number 15, 20 denotes the specified compressive strength (f ck) of 150mm cube at 28 days, expressed in N/mm 2. Thus, concrete is known by its compressive strength.

2017-12-14  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.
