Will my plan for putting up a 'makeshift' house with walls made of concrete work?

Question

I have revised my plan since my last question, but i know plan to post two pieces of drywall about 2-4 inches apart and then pouring concrete after adding support to the drywall.

Will this work and create a usable wall for a small house?

Should the walls be 2, 3, or 4 inches thick?

Do i need any more support within the walls to help them stand and last?

Answer 1

You need rebar first of all or the walls will fall apart, this means you need to know how to space and tie off rebar in the formwork (in your case the 2 sheets of drywall).  

Secondly the pressure of the concrete will blow out the drywall.  You should really be using ply with form release agent applied so you can pull the plywood off.

Third you need to properly vibrate the concrete to get the air voids out or you end up with an unsound wall.  

I don't want to be mean but I'm guessing you don't really know what you're up to.  If you do this wrong the walls will potentially collapse.  There's a reason we build things the way we do, it's because it works.  Cutting corners on something like this is a bad idea.

Answer 2

Concrete itself will crack and crumble without any support in it, It also will not pass safety codes.

Answer 3

This sound wild. By the time you add enough support to the drywall, you probably should use plywood and support. This wall would not support anything, probably not even itself. There is un-answered questions, why concrete?, this is a blind? Water proofing? Support? It would cost less (unless you get the concrete free) to build it out of wood and then sheet rock it. Please be really careful, your wall could fall over.
