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

A plain concrete with a large ratio aggregate to cement than structural concrete. It is used for filling and not structural duties

what is the concrete ratio in Class D2 concrete
M40 Concrete ratio 1:1.65:2.92 (cement:FA:CA)W/C ratio = 0.4As per Indian Standards.

Why does concrete mix with low water cement ratio resulted in hardened concrete having higher strength than those with high water cement ratio?
the strength of concrete is effected by water /cement ratio as the water/cement ratio increases the strength of the concrete decreases
A lot
In reinforced concrete construction, the modular ratio refers to the modulus of elasticity of concrete to that of steel. It is used in structural design calculations to determine distribution of stresses between concrete and steel in beams and columns.
There are different concrete mixes and the will depend on which mix it is. The material ratio will remain the same whatever the volume is.
There is no set ratio for a concrete requiring a compressive strength of m50. It is usually created according to the factors of the site condition and location.

simply workabilty is the w/c ratio in concrete. more the w/c ratio higher the workability and vice versa. and it is true that excess amount of w/c ratio doesnt give proper strength. so workable concrete i.e, concrete with proper w/c is must for good strength. *note: not considering the mix of concrete.
