If you don't care that the wood will rot in 5-10 years then its ok. A retaining wall will be battling moisture from the soil. I don't know if you are having that issue or not, but generally you want the front of the wall to breath. My first thought about this was that it's like putting a finished wall in an underground basement. So I was thinking, you may ...

It's a process, not a "special" material. A good steel trowel job can give a glass-like finish on standard concrete. It's partly technique, and partly timing (or timing is part of the technique.)

First I want to point out that the hardness has a lot to do with cure time and temperature. Longer cures (6-8 weeks) at cool temperature (say 50 °F) are harder. Short, hot cures are harder initially, and crumble later. Generally, the 1pt cement : 2pt sand ratio is best and will have a 3500 psi compression stress. A 1:3 ratio will have less than 3000 psi. ...
