Product Description Product Description     100% Polypropylene Stranded Fiber, Good Wear Resistance and High Strength Twist Fibers /PP Stranded Fiber   What is polypropylene fiber?       Polypropylene fiber is produced by special technology with 100% polypropylene as its raw   material, the products have net-like structure with many fiber monofilaments, with good dispersion,   no fascicles, and has a high toughness and strength.    What is the action principle of polypropylene fiber ?   When the PP Fiber is put into the concrete, the horizontal structure in fiber monofilament can be   destroyed in the course of stirring owing to friction and rubbing, and the fiber monofilament or net   like structure will fully stretch, thus the concrete is reinforced by a great number of polypropylene   fibers.     Mixing Process
Crushed stones, fibers and sands are put into the mixer in succession.   After stirring for two minutes; fiber will fully spread and then add cement and water and stir   normally.   The addition of materials also can be put into as usual, but the stirring time should be properly   prolonged to more than 4 minutes to make fiber completely mixed.   Dosage
Generally the recommended amount to add to the concrete is 3.0kg/cbm of concrete.     Technical Parameter
