Abstract: 
This paper shows the possibility to use bundles of wood fibres as reinforcement in cement-based materials for specific ductility requirements. The strength of the fibres, the bond between the fibres and the cement matrix and the matrix properties were measured. Then the composites were designed. Under four-point bending load the composites with 5.3% per volume of pine fibres and a low compressive strength cement matrix developed improved deflection capacity and multiple cracking prior to failure, independent from the specimen geometry. This lightweight material can be considered for applications such as low-budget housing in countries subject to seismic risk, where ductility and low weight are desirable characteristics of the building material.
