The most important benefit of papercrete is the reduction of cement in the mix. CO2 emissions during production, the total cost and weigh are reduced, resulting in a cheap and lightweight material. Paper fibers result in excellent heat and sound insulating properties.
Standard mix has not been established and there is no official data available about the structural behaviour and the long-term viability.
– Getting building permit is difficult.
– Papercrete is a brittle materials. It expands and contracts frequently leading to cracks and buckling and it has very low tensile strength
– Has to deal with the general perception of paper as being a weak material.
Papercrete has many imperfections that relate with the rarity of the surface. Creating homogeneous specimens with a smooth surface becomes difficult. However the rough-porous texture provides a very strong bond between the blocks and a potential facade material.
