With polypropylene as its raw material, this fiber was produced by special technology. The products appear net-like in 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 the fiber monofilament or net-like structure will fully stretch, thus the concrete is reinforced by a great number of polypropylene fibers.
Product features:
1. Prevent concrete crazing effectively.
2. Improve tensile strength of concrete.
3. Improve the concussion and resistance to wear of concrete.
4. Improve? Barrier property of concrete.
Application:
1. Projects like concrete road, bridge, airport road and factory floor which strictly require cracking resistance.
2. The walls of tunnels, mines, roofs and reservoir projects with special construction.
3. River courses and dams, etc.
4. Military defense works, dock banks and piers, etc.
Application construction:
19mm polypropylene fiber is suitable for the use of concrete; And 10mm for mortar concrete.
Compound amount: To resist the common cracks on surfaces, 0.9kg/m3 fibers are enough, and for bridge deck and tunnel sprayed
Concrete, 0.9~1.8kg/m3 fibers are enough;
Stirring requirement:
Put crushed stone, fiber and sand together, stir about 2 minutes, the fiber monofilament will fully stretch, then stir after putting cement and water. Also it can be mixed according common sequence but time for stirring can be prolonged for 4minutes in order to make the compound mix completely.&
