[papercreters] Re: Slip Form Follow-up Question

Dan,

(From reading others experience, not personal experience.)

To get the quick drying time, you will need to make small blocks. Maybe no more than 3 inches thick.

You will not be able to dry your roof elements in time, so to get the prototype built, you will need to use 2x4s, fiberglass insulation, tin roofing, etc for the roof. I hope to build a papercrete roof system, so I think that is possible, but it will require lengthy drying time.

I believe small blocks would work for the floor and walls. I believe that the floor would not be walkable, but could provide the R value you need. Maybe you could put down temporary boards to walk on when loading and unloading the kiln.

To improve the drainage from PC blocks, some people use shade cloth on the ground and then put the blocks on top. I would suggest trying 6" welded wire mesh, topped with 1" welded wire mesh, topped with two layers of shade cloth. (If you try something to improve drainage and drying, please let us know how it works. I am in a humid environment also and need to work out a way to dry blocks.)

Good luck. Please let us know what you try and what your results are.

Bobby
