Polypropylene mesh fiber is a bundle of fibers interlaced into a web shape, made from polypropylene granules through special processing and treatment. When added to concrete mix and stirred, the fibers form a fully expanded single fiber or mesh structure, creating a random support system within the concrete. It effectively controls the early plastic shrinkage and settlement cracks of concrete and cement mortar, significantly enhancing the concrete's impermeability, resistance to破碎 and impact, and its toughness and wear resistance. This greatly extends the lifespan of buildings and substantially reduces maintenance costs.

Cement concrete mesh fibers effectively control microcracking 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 crack-preventing fiber for concrete, concrete companion mesh fibers are becoming a hot topic in both research and application in the fiber 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, boost its frost resistance, and enhance the quality of concrete products.
