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?

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

In one cubic meter of M25 concrete, there are approximately 13.33 bags of 50 kg each. This is based on the standard mix proportion of M25 concrete, which uses 1 part cement, 1 part sand, and 2 parts coarse aggregates by volume.

The ideal cement and sand mix ratio for optimal strength in a concrete mixture is typically 1 part cement to 3 parts sand. This ratio helps ensure a strong and durable concrete mix.
Why does concrete mix with low water cement ratio resulted in hardened concrete having higher strength than those with high water cement ratio?
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.

The recommended mortar mix for concrete blocks is a 1:3 ratio of cement to sand.
Critical damping in the context of M25 concrete typically refers to the material's response to dynamic loading and its ability to return to equilibrium without oscillation. M25 concrete has a characteristic compressive strength of 25 MPa and is often used in structural applications. The damping ratio for concrete can vary, but for M25, it usually falls within a range of 0.02 to 0.10, indicating that while it has some energy dissipation properties, it is generally not considered highly damped. Critical damping is more relevant in dynamic analysis of structures rather than a specific property of the concrete itself.
