According to IS 456 The grade of concrete are 15, M10, M1,5 M20 (ORDINARY CONCRETE)
M25 M30 M35 M40 M45 M50 M55 (STANDARD CONCRETE).
& M60 M65 M70 M75 M80 (HIGH STRENGTH CONCRETE) So the actual answer is none.
M25 M30 M35 M40 M45 M50 M55 (STANDARD CONCRETE).
& M60 M65 M70 M75 M80 (HIGH STRENGTH CONCRETE) So the actual answer is none.

IS 456-2000 has designated the concrete mixes into a number of grades as M10, M15, M20, M25, M30, M35 and M40. In this designation the letter M refers to the mix and the number to the specified 28 day cube strength of mix in N/mm2. The mixes of grades M10, M15, M20 and M25 correspond approximately to the mix proportions (1:3:6), (1:2:4), (1:1.5:3) and (1:1:2) respectively.

According to IS 456-2000 grade of concrete are as follows,
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).
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).

I want make design for (M-30) what is the mix properties I can use and the details of max below.
OPC53.
