The ratios of cement to sand to aggregate for the different grades of concrete are as follows. M10 has a ratio of 1:3:6. M15 has a ratio of 1:2:4. M20 has a ratio of 1:1.5:3. M25 has a ratio of 1:1:2, but M30 has no set ratio. It is a designed mixture to achieve the stress tolerance desired.
It depends who is doing the testing and what tests are carried out.
what is the concrete ratio in Class D2 concrete
15 milligrams
Ans: M15 grade indicates the grade of concrete used in the structure i.e M indicates the design mix proporation and 15 indicates the compressive strength of conctrete at 28 days in N/mm2
