| Abstract: | Steel fibers are ferromagnetic and they have the property of altering the magnetic field around them. This paper discusses a method and gives a practical example to measure, non-destructively, the amount and orientation of fibers from cubic concrete specimens (150?mm). This is possible because the fibers affect inductance of a sensor (an inductive coil) that is wrapped around the specimen. |
