[papercreters] Re: Broken glass

Drinks bottles as a wall filler with traditional cement mortar is an established practice, and works fine as long as the wall is rendered to provde the necessary strength.

Empty bottles insulate better than concrete, but far less than papercrete, plus the resulting wall is much weaker than a solid one. So I wouldnt use them on an exterior wall.

I kinda sketched some ideas down but one idea was to fill the bottles with water and then when the wall was set up take a nail and poke them from the lower end before the wall completely dried. This would allow the water to drain out and then you have a large void in your wall that would act as an insulator. I actually got the idea from watching transformers when Sam and Makala hid in the adobe house in the desert. One of the walls in the house seemed to be built out of plastic bottles and adobe. Just a thought not sure that was what you were looking for though.

There doesnt seem to be much bonding between the papercrete and glass though, so tensile strength remains poor. It also reduced shrink during drying.
