Then mix the concrete to the required mix and add to the mould and smooth over
then band the outside of the mould to try get the air out
this will be the biggest problem with trying to get a smooth to getting the air out
You will also need to rum rebar through it for strength
Google diy concrete counter top

That is pretty much my plan but using melamin faced board instead of mdf. I'll go wit the coarse aggregate, maybe I'll even cheat and by a premixed bag. I'll post up my results once I've buggered it up.
