The product, polypropylene synthetic fiber, was created as a steel fiber replacement. In comparison to steel fiber, it is corrosion resistant, easy to disperse, simple to produce, and doesn't harm mixing equipment. A unique method and surface treatment are used to manufacture synthetic resin, which serves as the product's base material. It benefits from a strong grip, good dispersion in concrete, and great breaking strength. It has the qualities of tensile strength, shear resistance, crack resistance, fatigue resistance, and high toughness, and may replace steel fiber for cement concrete, overcoming the limitations of low tensile strength, low ultimate elongation rate, and brittleness of concrete. It has been used in the disciplines of hydraulic engineering, building, and road and bridge engineering.
