1.Introduction

Wave pp fibre is polypropylene as raw material, after special surface modification and molding processing. With acid corrosion, high strength, easy to disperse, easy construction, the mixing of the vehicle, the road without any damage, no special advantages of conservation, can substitute for steel fiber reinforced concrete crack in the cement significantly improve the impact toughness of concrete, anti-bending performance, and because of special cross-sectional shape, and a good combination of properties of concrete.
