With polypropylene as its raw material, this fiber-mesh is produced by special technology, The products appear net-like structure with many fiber monofilaments connected。
When the 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 ( more than 7 million pieces per sqm ) of polypropylene fibers。

Applying Instruction
Length: Generally, the proper length of the fiber added into the concrete is 20mm.
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.
Shaping & Maintenance: There is no Special requirement, may along the vibrating time for 30s. The maintenance of the fiber concrete should be done same as the normal concrete.
Package: 0.9kg per bag, may packed as customer’s requirement. |
