st4 is just a standard type concrete probably comparable to c40 structural concrete, pav 2 is the equivalent to c35 concrete with air bubbles, mostly used in paving works
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.
1:2:3
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.
1:1.5:2.5
The concrete that gives a compressive strength of 40 N/mm2 when its cube is tested.

what is the concrete ratio in Class D2 concrete
What is equivalent to c40 grade material
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
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.
