The distribution and orientation of fibers in the matrix have a great impact on the characteristics of strain hardening, multiple cracking and crack self-healing of engineered cementitious composites (ECC). Based on recent work on ECC fiber distribution, this review briefly introduced the characterization parameters and methods of fiber distribution. Effect of fiber distribution on the mechanical properties of ECC was represented from micro- to macro-scale. Three factors affecting ECC fiber distribution are fiber characteristics, matrix characteristics and molding process. In addition, some problems in the current research of ECC fiber distribution were also discussed, and the future research aspects were given.
