Title:
FIBER FOR REINFORCING CONCRETE AND CONCRETE MOLDING USING THE SAME
Document Type and Number:
Japanese Patent JP3755267
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a fiber for reinforcing concrete useful for working board, etc., having a large shock absorbing energy, capable of improving flexural strength and compressed strength of a concrete molding, showing excellent reinforcing effects, by making the fiber include a fiber of high elongation having a single fiber elongation of a prescribed value or higher than it.
SOLUTION: This fiber comprises (A) preferably 30-100 wt.% of a fiber of high elongation having ≥500%, ≥1,000% single fiber elongation, for example, a polyolefin-based fiber such as a polypropylene, etc., and more preferably (B) preferably 0-70 wt.% of a fiber of high strength having ≥5 g/d, preferably ≥7 g/d single fiber strength, for example, a polyolefin-based fiber, etc. Preferably at least one of the components A and B is coated with 0.1-10 wt.% based on the composition A or B of a surfactant which is selected from among a higher fatty acid metal salt, a higher alcohol sulfuric ester metal salt, an alkylbenzene sulfonic metal salt, etc., and contains a 8-22C alkyl group.
