In this M refer to Maximum compressive strength and 20 refer that concrete that with stand upto 20KN compressive strength.

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.
M20 give you strength of 20Mpa and M25 give you strength of 25 Mpa after 28 days of curing.
