Grade of Concrete is the classification of concrete according to its compressive strength.. For making concrete we use cement sand aggregate and water which are mixed with certain ratio and concrete is cast and put in a cube of 150 mm sie and put in a water bath for 28 days and afterward it is tested in a compression test.

M stands for mix. Mix represents concrete with designated proportions of cement sand and aggregate. And the number following M represents compressive strength of that concrete mix in Nmm 2 after 28 days. For example for M20 grade of concrete mix
Read MoreA standard 3000 psi concrete is equivalent to roughly 20 MPa. Some countries also define concrete types by compressive strength using a standard nomenclature not found in the U.S. In India for example concrete grades are rated using the letter M followed by a number where the number represents the compressive strength in MPa.
