Concrete fibers are high-performance fibers used in concrete or mortar, effectively controlling the micro-cracking caused by factors such as plastic shrinkage, drying shrinkage, and temperature changes in concrete or mortar. They prevent and inhibit the formation and development of original cracks in concrete, significantly improving the crack resistance and water resistance of concrete or mortar, enhancing its abrasion resistance, and increasing the tensile strength of concrete, thereby extending the service life of concrete.
Concrete fibers are produced by blending modified masterbatch with polypropylene pellets, followed by co-molding, spinning, and stretching. These fibers are treated with special antistatic and UV-resistant processes to ensure even dispersion in concrete, maintaining their effectiveness over long periods; the "Y" cross-section increases the fiber surface area. "Xin Si Wei" brand fibers, after chemical and physical modification, have a rough and porous surface, significantly enhancing the bond between the fibers and cementitious aggregates. Concrete fibers improve concrete performance by reducing the occurrence and number of primary cracks, and they do not conflict or undergo any chemical reactions with concrete aggregates, admixtures, blending materials, or cement, thus exhibiting good compatibility with concrete materials.
