Abstract: 
In hardened concrete fibres aligned towards direction of tensile stresses work most efficiently. During the casting of fibre reinforced self-compacting concrete (FRC SCC) fibres tend to orientate in accordance with the flow. This property of FRC SCC can be used to achieve a desired orientation by optimizing the casting process and mix properties and thus minimizing the fibre content for a given load. If flow induced fibre orientation shall be applied in the industry, methods for quality control of fibre distribution in FRCSCC elements and structures are needed. Such methods should characterise fibre orientation, spatial distribution, and amount of fibres. In this paper an overview of potential methods for quality control of fibre orientation, distribution, and amount is given. Some experience of working with image analysis, manual counting and CT is also presented.
