A detailed approach of aligning steel fibers in cement mortar using magnetic field was presented. Necessary magnetic induction of magnetic field and workability of fresh mortar for aligning steel fiber were suggested. X-ray CT test results showed that the steel fibers in hardened mortar was highly aligned. Aligned steel fibers significantly increase the efficiency of reinforcement on mortar.
