Title:
HIGH-STRENGTH POLYOLEFIN FIBER AND CONCRETE MOLDED FORM USING THE SAME
Document Type and Number:
Japanese Patent JP3960100
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide high-strength polyolefin fibers markedly improved in their anchoring effect on concrete in a concrete molded form containing them, prevented from being pulled off the molded form, having high single fiber tenacity, therefore suitable as concrete-reinforcing fibers.
SOLUTION: The high-strength polyolefin fibers are made mainly from a polypropylene resin and have a single fiber tenacity of ≥9 cN/dtex. The single fiber has a striated rough-surfaced structure formed along the curved fiber surface.
