A/c to IS 456: concrete mix designated in 7 grades.
M100,
M150,
M200,
M250,
M300,
M350,
M400.
For design mix Letter M refers to mix and number to specified characteristics compressive strength of 15 cm cube at 28 days in N/mm^2 or kg/cm^2.

1.Ordinary concrete- 5 (M5 to M20).
2. Stander concrete- 8 (M25 to M60).
3. Hight strength Concrete- 4 (M65 to M80).

According to IS 456-2000 grade of concrete.
Ordinary Concrete - M 10 to M 20(3 grade).
Standard Concrete - M 25 to M 55(7 grade).
High strength Concrete - M 60 to M 80(5 grade).
M5 1:5:10
M7.5 1:4:8
M10 1:3:6
M15 1:2:4
M20 1:1.5:3
M25 1:1:2
M30 As per Design
M35 As per Design

According IS 456-2000.
Nominal mix concrete is,
M10, M15, M20, M25, M30, M35, M40.
Nominal mix concrete is,
M10, M15, M20, M25, M30, M35, M40.

The number of grades of nominal concrete mixes, is 7:
M5, M10, M15, M20, M25, M30 and M35.
M5, M10, M15, M20, M25, M30 and M35.

What is the ratio of M30, M35 and M40?
Soniya said:

Above M30 Mix design is done because 5 ingredient of concrete will start above M30 i.e. cement, aggregates, water, admixture.
