You won't know for sure until you experiment with the stuff.  For my projects I mixed wallpaper glue and pulp and it gets pretty hard if you allow the time to dry.

To dry it faster I put them in the oven at a very low temperature and it didn't even smoke and dried up strong.  Try it and you will see.

maybe u can try using a frame made out of bars...
sorta like trusses.
one of my first year engineering project was building a bridge outta newspaper.
we brushed starch glue on the paper and then rolled the newspaper (with pencils and pens in da centre which would later be taken out) as tight as we could.
if done properly the results is quite strong to be used for axial stress.
it's not suitable for bending though.

Yes, Alan, the wallpaper paste you can get from Lowe's or a wallpaper store.

just use flour and water mixed in to a thick pancake consistency. . it works great as a binder. I agree, putting it in the oven at a low temp is a good way to get it to dry fast.
Personally, I think that using layers makes a stronger finished piece. You have to look at it like when it is in layers, it is actually like a woven piece of cloth compared to pulp, which is like a piece of felt that has no weave.
I think many people see the pulp as stronger because it's easier to get a good thickness with the pulp. with layers, you really have to have the patience to put a lot of layers together. then again, maybe I'm just wrong!
