Mechanical and electrical properties of magnetically aligned micro steel fiber‐reinforced self‐compacting concrete

Structural Concrete, Volume 26, Issue 6, Page 7653-7677, December 2025.
Abstract This study investigates the impact of magnetic alignment of micro steel fibers (0.35%, 0.70%, and 1.05% contents) on the mechanical and electrical properties of fiber‐reinforced self‐compacting concrete. A simplified magnetic circuit was designed and built to align the fibers within the concrete matrix.
