A key part in optimising the performance of fibre-reinforced concrete (FRC) lies in ensuring the correct orientation of fibres, especially in structural components where directional stress resistance is critical, such as beams and slabs. However, assessing the orientation of fibres in hardened concrete poses a significant challenge. This study explores the use of the non-destructive evaluation of fibre orientation within FRC by measuring a quality factor (Q-factor) of an electrical coil with an inserted FRC specimen. Through numerical simulations, the effectiveness of the Q-factor measurements were evaluated using several scenarios of fibre positions, quantity, and orientations. It was discovered that the Q-factor is sensitive to these variables and, therefore, it is a suitable tool for material diagnostics.
