Nominal mix concrete is said under M20 or lower & standard concrete grades are 7 i.e; m25 to m55.
These values are from IS 456:2000.

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

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

As per IS 456 ordinary concrete M10; M15; M20.
Standard Concrete M25 to M55.
High strength concrete is M60 to M80.
Standard Concrete M25 to M55.
High strength concrete is M60 to M80.

IS 456-2000 has designated the concrete mixes into a number of grades as M10, M15, M20, M25, M30, M35 and M40.

The correct answer =3 grades.
The concrete mix = M10 M15 M20.
Design mix= M25 -M55.
High Concrete up to M80.
The concrete mix = M10 M15 M20.
Design mix= M25 -M55.
High Concrete up to M80.

Yes, I.S. code is gave of concrete grade is 7.5, 10, 15, 20, 25 and according your design above 25 to 55.

M-5 to M-20 Ordinary Concrete.
M-25 to M-80 Standard Concrete.
M-85 to M-200 High Strength Concrete.
M-25 to M-80 Standard Concrete.
M-85 to M-200 High Strength Concrete.

Ordinary Concrete - M 10 to M 20.
Standard Concrete - M 25 to M 55.
High strength Concrete -above M55.
Standard Concrete - M 25 to M 55.
High strength Concrete -above M55.
