The inductive method is a non-destructive test which is capable to estimate both the fibre orientation and the fibre content in steel fibre reinforced concrete (SFRC) samples by the means of a coil and an impedance analyser. In this study, the theoretical basis of the method and the equations for assessing the content and orientation of fibres are given. Finite Element simulations are performed to estimate the parameters of the equations. An experimental program is conducted to evaluate the influences of two different coils and the temperature on the test. The results show that good accuracy and repeatability are obtained with both coils and no correction is needed for consideration of the impact of temperature.
