Summary:A preferential orientation of fibres is induced by the production process of fibre reinforced autoclaved aerated concrete. For a better understanding of the development of the fibre arrangement during the foaming process of the concrete, digital radiography was used to study the evolution of orientation in situ. The strength and the deformation behaviour of this building material are largely influenced by the fibre orientation. Therefore information on the fibre orientation is highly desirable. Computed tomography measurements allow for the non destructive investigation of the material. The contrast between fibres and concrete matrix is sufficiently high, even for glass fibres. Two different ways to study the fibre orientation are compared. The results correlate with the strength and the deformation behaviour of the samples. A high resolution study of the fibre environment shows that the fibres align the adjacent pores.
