7 grades of concrete

WebHere, “M” denotes the mix ratio of concrete and numerical value shows the value of grade of concrete. For example, If we take the M20 grade of concrete then, M shows that it has a mixture of cement, sand, and aggregate in 1:2:3 in proportion. And 20 shows that the compressive strength of concrete is 20 KN/ mm2.
