Anisotropy

Specimens don’t shrink symmetrically. The process of making the pulp (drill with special x-shaped head) distributes the fibres unevenly. From the existing specimens I could not define a dominant direction. Anisotropic materials properties vary with the direction of measurement( e.g. … Continue reading

Compressive and bending strength

Papercrete, especially the untreated one, has poor mechanical properties. The compression and bending test gave the following information. σpapercete≈0.90 Mpa (1/25 normal concrete, lower than soft woods) 3 phases elastic-plastic-after starting to crumble becomes stiffer

Availability and processibility

Papercrete is made from materials widely available and easy to found. Paper comes from a variety of sources and is usually without cost. Manufacturing processes are still not developed enough to facilitate its use. If we decide to go into … Continue reading

Cost-effectiveness

The total cost vary depending what kind of additives or reinforcement is used in the mixture. The untreated mixture lies in the cheapest end of lightweight concretes. Colorants, water and fire sealants increase the price. Low cost materials, lie to … Continue reading
