Polypropylene mesh fiber, a bundle of fibers interwoven into a mesh, is made from polypropylene granules through special processing. When added to concrete mix and stirred, it forms a fully expanded fibrous or mesh structure within the concrete, creating a random support system. It effectively controls the early plastic shrinkage and settlement cracks in concrete and cement mortar. This significantly enhances the concrete's impermeability, resistance to fragmentation and impact, and improves its toughness and wear resistance, thereby greatly extending the lifespan of buildings and reducing maintenance costs.

Polypropylene mesh fibers are a bundle of fibers, made by special processing and treatment of polypropylene resin, which are intertwined to form a mesh. They have a strong bond with the base material of cement concrete. When added to the concrete base material and mixed, they automatically expand due to the impact of cement, sand, and stone aggregates. They become individual filaments or interwoven multifaceted fibers, creating a random support system within the concrete. They effectively control the early plastic shrinkage and settlement cracks of concrete and cement mortar, significantly enhancing the concrete's impermeability, resistance to crushing and impact, and its toughness and wear resistance. This greatly extends the lifespan of buildings and substantially reduces maintenance costs.
