Alignment of steel Fibres Using Helmholtz Coil

Popis výsledku v původním jazyce

This article focuses on design and manufacturing of Helmholtz coils used for aligning the steel fibres in fresh concrete mixture for creating the Aligned Steel Fibre Reinforced Concrete (ASFRC).Long term goals of research and also the SCC mixture used for aligning the fibres in magnetic field generated by Helmholtz coil are described. Methodology of first experiments is presented. Early experiments were focused on examination of behaviour of single steel fibre in fresh concrete mixture exposed to magnetic field. Parameters of used coil and generated magnetic field are described with finite element model of Helmholtz coil. Movement of fibres during the alignment process is described and based on measured data. Manufactured Helmholtz coil is suitable for alignment of MasterFibre 482 fibres (steel fibres) in fresh concrete. The vertical movement is also measured and data are presented. The connection of vertical movement and alignment was not directly clarified with current experiment setup.
