[papercreters] Re: Pure cardboard slurry

I've got material that can make a blade I would say at least 2-3 times thicker than a law mower blade you suppose that would work? Can u add borax to the mix for fire retardency? Thanks in advance, Todd.

I find that the blocks are sturdier than the ones I put cement and clay/sand/gravel. If you pack the cardboard slurry in your forms they will not shrink a lot and they dry light and very easy to handle and I'm sure very good insulation. I will need to put in something for fire retardancy. The straw bale people spray the bales with a boric acid mixture. I will try that in a stacked and mortared wall. Who knows?

I think it was pretty well worn out to begin with. I am in the process of putting another differential in it so we'll see. I also found that the lawnmower blade I started with is not strong enough for cardboard so I made one out of 1 and 1/2 inch by 3/16 angle and ground a cutting edge on it.

As it turns out I have access to a lot of cardboard boxes that I'd like to utilize. Ive made some in small batches that came out ok using drill and stucco attachment. Will the McCain mixer do a better job pulping cardboard? Whats you general thoughts on using purely cardboard? BTW I'm new here so I look forward to learning from y'all thanks, Todd.
