Development of the magnetic methods for testing homogeneity of fiber- concrete structures and potential applications in the forensic engineering
Hobst, Leonard ; Bílek, Petr
The favorable properties of steel fiber can be used if we need to increase the durability of concrete tensile stress that exceeds its strength, cyclic stress or shock loads. The problem is the processing of steel fiber-concrete structure. Especially at higher concentrations of fibers. During the manufacturing process, the fibers are often unevenly distributed. Wires are often clustered, reducing the overall homogeneity and the quality of steel fiber-concrete structures. The paper deals with the development of the magnetic method using permanent magnets for monitoring the distribution of fibers in hardened steel fiber-concrete structures and comparative measurements on control samples.
