<P>PROBLEM TO BE SOLVED: To provide a concrete reinforcement cut fiber which exhibits excellent dispersibility in concrete and an enhanced effect of the improvement of the concrete performance such as mechanical strength. <P>SOLUTION: Th cut fiber for concrete reinforcement is composed of a polyamide-based fiber on which a treating agent is stuck. The treating agent has 115 to 140 mN sticking tension of water to the fiber in a 25°C atmosphere and 75 to 100% detachment rate in water. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
