Thanks Slurryguy. I forgot about that. I have personally archived all the posts and my own research about various fire retardants and will definitly use some form of fire retardant in my mix. This is a perfect example of the great value of this group. Judith

I have little doubt about Judith's experiences.
I urge GREAT CAUTION. Papercrete that does not have any cement
content can be HAZARDOUS in a fire situation.
Please make sure you build SAFELY. Borax, lime, or other materials
can be added instead of cement to limit it from sustaining
combustion. Make sure you DO SOMETHING to the paper to keep if from
burning.
COMPLETELY UNTREATED paper blocks can be ignited by a very small
spark and very slowly smolder for hours or even days and completely
turn to ash.
This subject has been posted about frequently. Many messages are in
our archives. "burn" "fire" "smolder" "borax" "flame" are all good
search terms to help you find past messages on this topic.

working with papercrete for over 2 years. It takes a lot of energy
but is very rewarding and keeps you in shape. Anyway, I wanted to
comment on your uses for papercrete. I would say that when used as
insulation it would be best to leave out the cement. I use pumice
fines in place of sand and don't really know how to advise you on the
sand. I'm sure you will get a lot of suggestions. I know some are
adding vermiculite. ground up styroform and other clever things. I
was having a bad day one time and forgot to add the cement to the
mix. What I ended up with was a big rice cake like thing. It was
incredibly light but firm. I just interspersed the resulting blocks
throughout the wall. But now I am planning to expand my small shed
and make it into a little cabin for myself. What I want to do is make
large sections of papercrete without the cement and use it as roof
insulation. I can also attach it somehow to the exterior walls and
plaster over it. It takes natural plaster well. Regarding your
pavers, I'm not sure papercrete would be a good choice. I have had
papercrete blocks sit in puddles of water and completely fall apart.
I use very little cement in my mix. Perhaps with more cement they
would work especially if you laid them down over a base of gravel
that would drain the water away. Good luck to you. Judith

Papercrete sounds like it might be one way to go about it if I knew
how.I am joining this group to get educated. I have access to
discarded newspapers and can get cement from Lowes.I would also like
to use it in making pavers for my outside yard and maybe even patio
blocks. I will go look through the site and see what I can find on
this subject.Thank you for having meflorence in southeast florida
