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 fiber strand or mesh structure, creating a random support system within the concrete. 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 service life of buildings and reducing maintenance costs.

Cement concrete mesh fibers effectively control microcracks caused by factors such as concrete plastic shrinkage, drying shrinkage, and temperature changes, preventing and inhibiting the formation and development of cracks. As a new type of anti-crack fiber for concrete, concrete companion mesh fibers are becoming a hot topic in both research and application in the fiber-reinforced concrete field, following glass fibers and steel fibers.

Improve the homogeneity of concrete, enhance its fire resistance, reduce the brittleness of high-strength concrete, improve its impact resistance, wear resistance, and flexural strength, enhance its frost resistance, and elevate the quality of concrete products.
