In M20 grade concrete mix, what is M and what is 20? - Quora
Answer (1 of 5): M is mix. 20 is characteristic compressive cube strength after 28 days. Note that Characteristic strength is not compressive strength of concrete. It is only the cube strength. But actual shape of concrete member in our construction is not cube. So the strength is based on cylind...
