Abstract Bio-sourced materials combined with a cementitious matrix offer an interesting alternative to traditional construction materials. To contribute to their wider acceptance by the sustainable construction market, an investigation into the use of wood-cement composite panels as stay-in-place or permanent formwork is presented. As individual panels, the mechanical performance was evaluated through three point bending tests . But, as part of the formwork system, their overall structural performance was evaluated through finite element simulation under the action of lateral pressure exerted by the concrete in a liquid state. The Concrete Damage Plasticity Model (CPDM) available in the Abaqus code is adapted and used to model the mechanical behaviour of the wood-cement composite. The obtained results show wood-cement composite panels offer a promising alternative for the development of a lightweight permanent formwork system, that can contribute to the thermal and acoustic comfort of green buildings.
