Gel space ratio is the ratio of volume of hydrated solids in pores to the total volume of pores available before hydration. It's given by
X = (volume of gel) / (volume of gel + volume of pores)
where Gel is solid hydrated product
Why does concrete mix with low water cement ratio resulted in hardened concrete having higher strength than those with high water cement ratio?

The modular ratio of concrete is a measure used in structural engineering to relate the elastic moduli of concrete to that of reinforcing steel. It is defined as the ratio of the modulus of elasticity of steel to the modulus of elasticity of concrete. This ratio helps engineers determine how much the two materials will deform under load and is crucial for analyzing the behavior of reinforced concrete structures. Typically, the modular ratio for concrete is around 8 to 12, depending on the specific types of concrete and steel used.
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
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.
