REINFORCING FIBER, METHOD FOR PRODUCING THE SAME AND CONCRETE MATERIAL REINFORCED BY THE SAME FIBER

摘要

PROBLEM TO BE SOLVED: To provide a reinforcing fiber remarkably improving reinforcing effect by fiber, capable of providing uniform fresh concreted, not impairing workability of kneading, etc., and to provide a concrete material reinforced by the fiber. SOLUTION: The concrete material is reinforced by a reinforcing fiber obtained by fixing a silane coupling agent and/or a titanium coupling agent and a water-soluble polymer to the fiber surface.
