No. I think heavy water is the mostly used moderator used in the nuclear fission.

What concrete not used?
The whole reactor is encased with thick concrete wall.

Concrete can never be used as a moderator. Rather it is used as a protective shields to protect from neutrons and gamma rays.

D20 heavy water is used as moderate in N.P.P.

In nuclear power plants, heavy water (D20) is mostly used as a moderator to slow down fast moving neutrons released in fission process and in sometimes graphite may be used but concrete cannot be used.
Concrete is used to make a protective shield of about 5 to 6m thick to avoid the neutrons and ultraviolet waves escaping from the reactor.
