Re: [papercreters] Additives



Im interested in your mention of Forta fiber ( what that is ). I use glass fiber when making surface bonding mortar, for styrofoam blocks. Also I use acrylic (used paint ), it takes a lot ( like 2 gallons per sack of cement) I use pozzolan to react the lime in the portland. Things like superplastisizer and air entrainment , seem to get lost in the mix ( not much value ).

Many thanks for this formula. Along with Raf's question, could you help us to scale it down to the five-gallon bucket size?
Also, would adding reinforcing fibers (Forta-Fiber, or like kinds) add to the papercrete strength, and perhaps reduce shrinkage during drying? And just one more question, would use of a small amount of a superplasticizer help to decrease the water/cement ratio, to help increase the final product strength? I realize that such considerations are more relevant in large-scale mixes and pours, but I respect your experience and expertise.
Mahalo for your reply.

Im sure others may disagree, still after 1000 mixes i find the following to be the strongest most productive mix to be as follows -
Make mortar and add paper - Mortar typically is made with 3 of aggregate and one of cement - then add newspaper fiber - For instance, in one yard of material (27 cubic feet ) Half the mix would be fiber (approx. 80 pounds ) the other half would be  about 12 cubic feet of sand, perlite, or pumice, does not matter which, filled with 3 cubic feet of cements. Cements should be adjusted with 10 to 20 percent of pozzolonic material for the fastest cure and to get rid of the excess water that is held by the excess of unreacted calcium hydroxide in the cement - More later- ask questions _ Clyde T Curry

What is the most common aditives used in some papercrete formulations?. I understand there are some compounds used for curing, glueing, insect repellent etc. Pls, give me some info. I am new. Thanks
