Thank you for your insight on rebar. I have always felt that rebar was a waste of effort and money, after seeing how the papercrete shrinks away from it over time. I will add that I think it is actually a detriment to the strength of the papercrete because it would introduce a rigid member that would cut through the papercrete in the event of an earthquake or other natural disaster. I am interested to hear from anyone with experience in this area. Is there anything that would perform as rebar would but would not compromise the integrity of the papercrete? I think the papercrete on its own would be great in a storm or earthquake. It seems like whenever I see earthquake footage on the news it is the inflexiblilty of the earthen buildings that causes them to fall. Ideas anyone?

Rebar in papercrete ends up being surrounded by a void and does not add much strength, other than holding pieces together if you should hit it with a truck or something, or if you live in an earthquake zone. IMHO in most cases rebar is a waste of money in this application.
4" panels will give you around R9-12 which is not a lot by modern standards. I'd recommend at least 6" and preferably 12" thick.

Hi everyone. first I also wana thank the moderators- keep doing what ever it is you do so well, so WE ALL can have a good time connecting to each other. second, I wanted to ask; has anyone tried to make a PC block consistnig of 2 different mixtures? if so can you describe it & for what purposes? The reason I'm asking is because I'm thinking of producing insulating panels that can be attached to the outer surfaces of existing houses, meaning, I want slim panels (2-6 inch thick) with a lot of R-VALUE (inner layer- High on fibers, less on mass- OPC, dirt etc.)on the one hand but it durable to climate (outer layer- Low on fibers, High on mass- OPC, dirt, Lime etc.) on the other Also, I wish to minimize the use of wire mesh, rebars or any kind of extra reinforcement which is not a part of the PC mix. so anyone? experience? thoughts? am I shooting to high here? Plus, How big do you think the panels should be? I think they should be at least 10 cm (4 inch) thick, and thinking of 60x120 cm boards. still thinking about connections to the wall as well. would love to get ideas udi --------------------- --------- ------ Yahoo!
