Is a high-strength polypropylene monofilament fiber bundle, with a special surface treatment technology, to ensure that the fiber has excellent dispersion in concrete and cement bond strength of the body. Generally used in fine aggregate concrete. Concrete fibers (Concrete recommended 12-19mm dedicated fiber strength concrete crack a big effect.) Tensile elongation at break of more than 15-25% 500mpa elastic modulus> 3800mp1, effectively improve the crack resistance of mortar, concrete. Experiments show that: Compared with ordinary mortar / concrete, such as adding volume content of 0.1 percent (about 0.9Kg / m3) monofilament fiber, crack resistance mortar / concrete is increased by 70%. 2, greatly improving the impermeability of concrete. Polypropylene monofilament fiber bundle concrete 0.9Kg / m3 content than ordinary concrete impermeability capacity increased by 60% to 70%. 3, significantly improving impact resistance and abrasion resistance of concrete. Polypropylene fiber, although low stiffness, poor load transfer capability, but can absorb impact energy, effectively reducing the fracture, enhance the continuity of dielectric material, reducing the local stress concentration caused by the shock wave is blocked, which can greatly improve concrete impact resistance and toughness. 4, to improve frost resistance of concrete. In concrete added polypropylene fibers, can ease the temperature changes caused by the internal stress of the concrete, preventing cracks extended temperature; at the same time, to improve concrete impermeability is also beneficial to improve the ability of anti-freeze. Practice and studies have shown that adding polypropylene fibers in concrete can be used as an effective means of concrete cracking temperature difference compensation. 5, to improve the quality of concrete products, effectively keeping products edges, corners, surface integrity, make steel from corrosion within the article. Fiber mortar (mortar recommended 3-12mm mortar dedicated fiber spread of good toughness can effectively prevent pilling) (1) crack resistance, prevent mortar matrix and expand existing defects effectively delay the appearance of cracks. (2) impermeable: improve the density of the mortar matrix and prevent outside moisture intrusion. (3) durable, improve mortar matrix antifreeze, anti-fatigue performance, increase its durability. (4) impact: improve the mortar matrix tolerance deformation, thereby improving the toughness and impact resistance. (5) Tensile: Using fiber can play a role in improving the tensile strength of the matrix. Performance mortar fiber ratio: Mortar added fiber is mainly to give the mortar a certain toughness, crack resistance improving mortar, inhibit the production of the early cracks in the mortar, mainly has the following functions: (1) crack resistance, prevent mortar matrix original defect expansion and effectively delay the appearance of cracks. (2) impermeable: improve the density of the mortar matrix and prevent outside moisture intrusion. (3) durable, improve mortar matrix antifreeze, anti-fatigue performance, increase its durability. (4) impact: improve the mortar matrix tolerance deformation, thereby improving the toughness and impact resistance. (5) Tensile: Using fiber can play a role in improving the tensile strength of the matrix. (6) high toughness: mortar fiber with high strength and toughness, not easy to play in the mortar mixing bent ball, polypropylene fiber mesh appearance of a plurality of single fibers from each other cross-linking network structure. When after polypropylene mesh fiber into concrete, the concrete mixing process, the lateral connection between single fibers through the concrete itself rubbing and friction and destruction, formation of single fibers or mesh structure fully open, in order to achieve the number of Polypropylene fibers are uniformly incorporated many concrete results. Engineering polypropylene fiber is a new type of concrete reinforcing fibers, known as concrete "secondary ribs." Incorporation of polypropylene fiber concrete quality has been improved, comprehensive performance is improved. Having a mixing process is simple, inexpensive, high-performance characteristics. As a new type of concrete reinforcing fibers, polypropylene mesh fiber is becoming
