Concrete mix ratio for various grades of concrete

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 .
