Look up this video on You-Tube "Sidlakan Brick Manufacturing Technology" I just saw it after I made those last two posts so now I am sure rice hull ash will make a good brick. In your case I don't think you would have to fire it to make an actual brick material. Just mixing in the clay with the ash should do the trick for earth bags and or compressed earth or adobe blocks
Try letting the mold completely eat a big vat of raw rice hulls and water mixture first. After it is done completely molding dry out the mess and burn it in a rocket stove. When done you should have very nice pile of almost pure silica rice hull shells with no regular organic matter left. Perfect material for fire bricks or for mixing with clay for insulating building blocks.
Owen, I believe rice hulls will still maintain their insulative characteristics even if they were already burned but I do not believe mold would be able to grow on them. So you could use as much water and hulls as you wanted. Also might make a good fire brick? Rice hulls are like little shells of silica with a thin inner layer of more typical organic plant material so even after the organic material is gone the insulating silica shell remains.
Borax?
