Mortar Concrete Fiber

Concrete fiber is a high-performance fiber used in concrete/mortar, which effectively controls microcracks caused by factors such as plastic shrinkage, drying shrinkage, and temperature changes in concrete/mortar. It prevents and inhibits the formation and development of primary cracks in concrete, significantly improves the crack resistance and impermeability of concrete/mortar, enhances the toughness of concrete, thereby extending the service life of concrete.

Concrete fibers are produced by blending modified masterbatch into polypropylene pellets, followed by co-molding, spinning, and stretching. These fibers are treated with special antistatic and UV-resistant processes, ensuring even dispersion in concrete for long-lasting effectiveness; the "Y" cross-section increases the fiber surface area. "Xin Si Wei" brand fibers are chemically and physically modified, resulting in a rough and porous surface, significantly enhancing the bonding strength between the fibers and cementitious aggregates. Concrete fibers improve the performance of concrete by reducing the occurrence and number of primary cracks, and they do not conflict or undergo any chemical reactions with concrete aggregates, admixtures, additives, or cement, thus exhibiting good compatibility with concrete materials.
