Polypropylene Short Fiber significantly improves the crack resistance, impermeability, abrasion resistance, freeze-thaw resistance, and explosion resistance of mortars and concrete while enhancing the workability of the concrete mix. Millions of fibers are evenly distributed throughout the mortar/concrete, providing excellent micro-reinforcement, maintaining the integrity of the structure, and preventing it from breaking into numerous pieces during impact damage. This helps to prevent the corrosion of reinforcement bars within the structure and greatly extends the service life of the project, reducing maintenance costs. Its applications include cement mortars, explosion-proof and fireproof engineering, sprayed concrete, and rigid waterproof structures in concrete.
