Mechanical properties of high-performance concrete with steel fibres oriented by an electromagnetic field

Popis výsledku v původním jazyce

In order to achieve better efficiency of dispersed fibre reinforcement in cementitious composites, manufacturers need to be able to directly control the fibre orientation. The magnetic orientation of fibres is an effective way to align fibres in the desired direction of the main tensile stresses and significantly improve the load-bearing capacity of the composite material. In this study, cementitious composites with different percentages of fibre reinforcement were subjected to the magnetic fibre-orienting process and their resulting mechanical parameters were examined. Also, a non-destructive method was used to evaluate the fibre orientation and volume. The flexural strengths and the capacity to dissipate mechanical energy were improved considerably compared to the reference non-oriented specimens. The non-destructive method was also reasonably accurate to predict these results.
