POLYPROPYLENE FIBER FOR REINFORCING CEMENT

摘要

PROBLEM TO BE SOLVED: To provide a polyolefin resin fiber for reinforcing cement by which hydrophilicity is given to the fiber, which has excellent adhesive property to cement matrix and by which a cement formed material is reinforced to improve the bending strength or the impact strength. SOLUTION: The polypropylene fiber for reinforcing cement contains 1-10 pts.wt. multiple structural graft copolymer constituted of 50-90 wt.% segment of an ethylene-vinyl acetate copolymer and 50-10 wt.% segment of a vinyl polymer to 100 pts.wt. polypropylene.
