Here in the Arizona Outback it has been warm for quite a spell. I've recently got a tow mixer made and have made several batches of blocks. I am experimenting with different recipes and I've come to some interesting conclusions. I have a very fine clay soil here, 100% clay as a matter of fact. The last two batches of blocks I made with very little clay and the rest pulp. I am using cardboard for pulp which has some interesting characteristics. It does not break down into cottage cheese type pulp like newsprint but rather into bigger pieces along with smaller ones and it seems to bind together very well. I have quit adding cement to the mix. It takes longer to dry, but once dry, well it's dry. And very hard. Of course it will absorb water but so does papercrete. I made some blocks and panels out of cardboard pulp alone and once dry it is very hard and rigid. I recently purchased online 50 pounds of boric acid and I will be experimenting with spraying the blocks to act as a fire retardant. Perhaps adding it to the mix as well. I soak the cardboard before pulping as that speeds the process up considerably. I also have a considerable stack of newspapers but I thought I would use them for a pc stucco mix. I haven't built anything yet but I will post some pictures of what I've got going.
