Product Name:  Synthetic Polypropylene Macro Construction Engineering Fiber 

 

Polypropylene macro fiber is a synthetic fiber for construction and engineering. It is widley used in modern engineering construction due to its properties of reinforcement and toughness for concrete. This kind of PP

macro fiber combines the advantages of both steel fiber and synthetic fiber, so it can control the crack and increase the toughness and impact-resistance.

Compared to steel fiber, polypropylene macro fiber has the advantage of corrosion resistance, easy dispersion, low cost and no harm to the equipment. That’s why synthetic polypropylene macro fiber

are widely used in construction and engineering.

Function:

 

 1. Synthetic polypropylene macro fiber has the properties of crack resistance and reinforcement, so it can replace the steel fiber, which will be more convenient and economic than steel fiber.

2. Polypropylene macro fiber can restrain the crack caused by the shrink, sedimentation of concrete and the temperature.

3. Improve the wear-resistance, impact-resistance of concrete.

4. Improve the reinforcement of concrete.

5. Improve the durability of concrete.

6. When used in shotcrete, PP macro fiber can decrease rebound and shrink, which is very convenient for construction.

7. Improve freezing& thawing resistance, fatigue resistance, and seepage resistance, thus prolong the lifetime of concrete.

 

Applying field:

 

1. Surface of road and highway.
2. Toll station, Concrete panel, Factory floor, Tunnel, Roof, Parking lot and Wharf of the port..
3. Bridge project, Water conservancy project,

Use instruction:

1. Add 3-8g polypropylene macro fiber per cubic meter of concrete.
2. 30-54mm polypropylene macro fiber for reinforcement, but 20-30mm for shotcrete.
3. Put the crushed stones, sand and fiber into the blender at the same time, stir them up. Then add water into it and continue to stir until they mix completely. 

Packing:
