Schlangen, H.E.J.G. Faculty Civil Engineering and Geosciences Department Structural Engineering Date 2010-05-23 Abstract Wood fibres can be a low cost reinforcement for cementitious materials for structural applications. In order to design a ductile cementitious material reinforced with softwood fibres the fibrematrix interface properties are studied. Pullout tests have been carried out to determine the bond strength and the influence in the pullout behaviour of the physical, chemical and mechanical properties of both the fibres and the cement matrix. Other fibre-matrix interface characteristics have been evaluated using an Environmental Scanning Electron Microscope (ESEM), a CT-scanner and optical microscopes. Matrix and fibre must be suitably designed in order to allow the fibre to be pulled out without rupture. A controlled mode of telescopic bonding during the pullout will be beneficial to increase the dissipated energy and develop ductility in the composite. Understanding the pullout behaviour in detail will be useful in the development of wood fibre reinforced cementitious materials.
