Static and long term compression behavior of hemp shiv for floating floor application

Densities of hemp shiv for building: From multiscale characterisation to application

“…when rearrangement and filling of small voids occur or when plastic deformation and fragmentation occur. Tronet et al (2014) and a later study (Chiasson-Poirier et al, 2020) observe that this model is in very close agreement with the compression behaviour of bulk hemp shiv (dry or wet) and lime and hemp mixtures (dry or wet), considering only the two first steps (Eq. ( 13)).…”

“…• Compacted: shiv is compacted manually using a wooden structure, up to saturation point following the protocol of Chiasson-Poirier et al (2020).…”

“…and these bundles are distinct for compressive stresses higher than 15 MPa. At lower stresses, the initial bulk density and internal and wall-die frictions could dramatically affect the packing's compressive behaviour, as shown by Tronet et al, (2014) and Chiasson-Poirier et al (2020). By zooming in on the experimental curves (Fig.…”
