Bulk Density and Compressibility
Abstract Hemp is made of highly deformable particles. Depending on the water content, on the particle size distribution, and on many other material parameters such as initial porosity and retting of the processed stalks, the mechanical behaviour of shiv in bulk can change significantly. In a compaction process, the mass per volume of the raw material increases with the applied stress and some creep or relaxation effects occur as observed in wood based materials. Hence, the mechanical properties of the bulk impact the packaging of the raw material as the shiv density inside the final mix and the in-service properties of the composite material. In this way, the bulk compressibility is primarily useful to manage the building processes, from transport of the raw material, to mixing and casting.
