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.
Why does concrete mix with low water cement ratio resulted in hardened concrete having higher strength than those with high water cement ratio?

1:1:2
upto M25 it is nominal mix but after that are the design mix which need to becalculated.....

For nominal Mix Cement consumption for M25 will be 570 kg per cum. and for Design Mix it can be optimised to 510 kg per cum.
1:1.5:2.5
the ratio is 1:1:2... so 1 bag of cement is used..ie; cement:sand:aggregate....
