Re: [papercreters] Use of fly ash



The use of less water in concrete will not carry over to papercrete in general because you have to have enough water to pulp the paper, which is a lot more than you would use for the equivalent amount of cement for concrete. Workability is probably not going to change much either since pc is already like potter's clay in workability. It may slightly affect the cost of the mix - if flyash is cheap and local.

Browsing in Scribd, as suggested by Charmaine,  I found an article on fly ash.  I think it says that we should put as least as much fly ash in our papercrete as concrete.  Fly ash is little spheres of glass, so it increases the insulation.  It improves the properties of the concrete.  It makes it more workable and allows the use of less water.  It should reduce the cost of the mix. Hopefully, these advantages will carry over to papercrete.
