IS 456-2000 has designated the concrete mixes into a number of grades as M10, M15, M20, M25, M30, M35 and M40. In this designation the letter M refers to the mix and the number to the specified 28 day cube strength of mix in N/mm 2 . The mixes of grades M10, M15, M20 and M25 correspond approximately to the mix proportions (1:3:6), (1:2:4), (1:1 ...

M20 grade of concrete and their mix ratio,hi guys in this article we know about grade of concrete and m20 grade of concrete mix ratio and ratio of grade of concrete like m5, m 7.5, m10, m15, m 20, m25 and so more. There are two types of concrete plain cement concrete (PCC) and reinforcement cement concrete (RCC).

Here M is grade of mix ratio and numerical value 5, 10, 15, 20…etc are strength of concrete in KN/mm². So, if we have M20 grade concrete then we can say that its grade is 20KN/mm². And mix proportion is 1:1.5:3 which indicates that in this types of mix ratios 1 part is cement, 1:5 part is sand and 3 part is aggregate has been used to make ...

"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 N/mm 2 after 28 days. For example, for M20 grade of concrete mix, its compressive strength after 28 days should be 20 N/mm 2.
