Experimental testing of the electromagnetic coil – determining the range of electromagnetic coil

IOP Conference Series: Materials Science and Engineering, 2018
The principle of steel fibre reinforced concrete structures is a uniform distribution of steel fibers in the given volume (structure or structural element), which, however, is not always possible to guarantee in the production. This is closely related to a problem of performing diagnosis of the existing steel fibre reinforced concrete structures ...
