Papercrete use is limited to experimental and recreation purposes. It is most commonly used as insulating material because of the high R-value. It΄s also been used as an in-fill wall in conjunction with structural steel beams, as mortar between dried “bricks” and a sub-layer for concrete flooring. The mix can be spread on interior or exterior surfaces for a stucco-like appearance.
The most common way that papercrete is used is in blocks. Econovate and Green Star Box are the only companies that commercially produce blocks. Papercrete can be sprayed on framework above layers of chicken wire or formed into prefab building units. Finally in can be used in monolithic pours but the problem is that the mix concentrates more in the bottom than at the top (uneven density).
