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

This study focuses on the compression behavior of hemp shiv layers for bio-based floating floor applications. An experimental campaign was performed to measure the instantaneous and creep behavior of different hemp shiv. The effect of humidity was also taken into account. A model was developed to assess both instantaneous and creep behavior of the shiv layer. The model validity ranges from a compressive stress of 0 to 5 kPa and with moisture ratio up to 20% in mass. It was used to define the maximum acceptable initial height of the shiv layer to guarantee a limited long-term deformation. These modeling and experiments lead to recommendations for application.
