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 this concrete.
