China Supplier PP Polypropylene Twist Fibers for Concrete Reinforcement

Polypropylene Twist Macro Fiber is developed for replacement of steel fiber, with polypropylene as its raw material;

It is produced by special drawing twisting and surface treatment.

Compared with steel fiber, it has advantages of acid, alkali resistant, excellent tensile, easy dispersing,

convenience for construction and no damage to the mixing equipment. Polypropylene Twist Bundle Fiber

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 per cubic meter of concrete.
