The strain-hardening behaviour of cementitious composites is the result of a synergistic behaviour of the cement matrix and fibres in a cracked cross-section. The distribution and orientation of the fibres are essential in order to obtain such favourable tensile behaviour. Strain-hardening composites can be applied and are especially useftil in structures, which are difficult to reinforce effectively with traditionally placed rebars. Examples of such structures are slender and thin elements, like double-curved precast panels, which also do not provide sufficient concrete cover. An experimental study was executed on the effect of the production method on the performance of panels produced with self-compacting fibre reinforced concrete. Different casting methods were applied such as free f l ow condition and controlling the flow by guides. Flexural tests were executed that indicate the influence o f the casting method. The distribution and orientation o f the steel fibres was studied by image analysis on pictures taken from cut cross-sections. This paper discusses results of a study that aimed at utilising the potential and improving the performance of self-compacting fibre reinforced concrete for the case of thin panels.
