Product Description
Product Description Polypropylene PP Stranded Fiber Reinforced Fiber High Strength Instead of
Steel 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.
