Vita Polypropylene chopped Fiber (PPMF) is a high-strength bundled monofilament fiber made of polypropylene resin as the primary raw material by a unique process. Adding it to concrete (or mortar) can effectively control micro-cracks caused by plastic shrinkage, settlement, and temperature changes in concrete (or dry mortar) and prevent and inhibit the formation and development of cracks. As a result, it can be widely used in industrial and civil construction, water conservancy engineering, road, and bridge engineering. ★Anti-cracking effect on concrete Concrete accompanying fibers are three-dimensionally distributed in concrete, effectively reducing the stress concentration at the tip of micro-cracks and preventing the occurrence and expansion of micro-cracks. ★Improve the impermeability of concrete The uniform distribution of PPMF in concrete forms a support system that reduces the bleeding of concrete and significantly improves its impermeability. ★Improve the freeze-thaw resistance of concrete Because PPMFr can effectively reduce the concentration of tensile stress in concrete caused by multiple freeze-thaw cycles, prevent the further development of micro-cracks, and help improve its freeze-thaw resistance. ★Improve the impact resistance and toughness of concrete PPMF helps to absorb the kinetic energy of concrete components when impacted, and due to the crack resistance effect of threads, it can effectively enhance the impact resistance and toughness of concrete.
