Synthetic macro fiber 54mm made by Polypropylene is an alternative product developed for steel fiber. Compared with steel fiber, it has the characteristics of acid and alkali resistance, high strength, easy dispersion, easy construction, and no damage to mixing equipment. Coarse polymer fibers are made from polypropylene through special parallel wire drawing and stranding molding processes and surface treatment. They have the advantages of high fracture strength, good dispersibility in concrete, and strong gripping force. They can be used instead of steel fibers for crack resistance and reinforcement of cement concrete.
