Abstract

A macro-synthetic fiber includes three or more partially fused filaments made of a polymer composition including at least one polypropylene, wherein the fiber has a multi-lobal cross-sectional shape with three or more lobes. A method produces macro-synthetic fibers, a cementitious material includes a binder and macro-synthetic fibers, and a method for forming a concrete surface uses a concrete mixture modified with the macro-synthetic fibers.
