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
The tensile strength of concrete is 10% of it's compressive strength.
the moisture of concrete is main strength for reinforced concrete structure
how does the fineness modulus of aggregate affect the strength of concrete
fcu is defined as a characteristic strength of concrete fy is the characteristic strength of steel
ST 4 concrete is the stronger out of the two. ST4 is equivalent of 16 kn at 28 day strength where as ST2 is only 8 kn at 28 day strength.

Yes, the characterisrtic strength of a concrete is the same as the compressive strength
the moisture of concrete is main strength for reinforced concrete structure
tensile strength is approximately between .08 to .15 of compression strength in concrete
Concrete with compressive strength more than 55 MPa is known as high strength concrete.It is used in the construction of bridges, dams. etc.,High strength concrete is produced by adding normal constituents of concrete with admixtures.

fcu is defined as a characteristic strength of concrete fy is the characteristic strength of steel
The equivalent concrete for M-30 cylinder strength is M-40 cube strength
Cylindrical strength = 85% of Cube strength.
