M20 Mrefers to mix and 20 refers to 20 n/mm2 strengh
and M200 mix 200n/mm2
M20
Required slump height of M20 for different concrete structures, are normally calculated by the required slump value, which would come out to be 100 lits.
20kn/mm2
M20 refers to the grade of the concrete generally used in construction purpose. Here, M refers to mix & number 20 refers to the characteristic strength of concrete. the proportions of this grade is (1:1 1/2: 3). Along with this there are some more grades used in constructions i.e., M5, M7.5, M10, M15, M25, M30................. M80
M20 grade - 1:1.5:3Cement required - 360 kgs per m3Cement required - 7.2 bags.

1:2:4
it is concrete mix which gain strength 20kn/mm2 in 28 day of curing....
M20 give you strength of 20Mpa and M25 give you strength of 25 Mpa after 28 days of curing.
