Specifications

1) More economic than steel fiber
2) Easy to disperse
3) High gripping force
4) Combine of steel fiber and synthetic fiber

Product Name:  New Top Quality Engineering Plastic Material for Tunnel 

 

Replicated Steel PP Fiber is also called plastic steel fiber. It is a toughening synthetic macro fiber with high strength which is widely used in building and bridge projects. This kind of plastic fiber combines the advantages of both steel fiber and synthetic fiber, so it can control the crack and increase the toughness and impact-resistance.

 

Detailed pictures:

 

Compared to steel fiber, it has the advantage of corrosion resistance, easy dispersion, low cost and no harm to the equipment. That’s why Replicated Steel PP Fiber are widely used in construction.

Function:

 

 1. Replicated Steel PP 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. Replicated Steel PP 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, Replicated Steel PP 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 Replicated Steel PP Fiber per cubic meter of concrete.
2. 30-54mm Replicated Steel PP 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.

Advantage:

 

The Macro Fiber is made according to the function of the steel fiber. Its shape of cross section and specific surface area are similar to the steel fiber, so when compare the economy of the two kind of material, we could suppose that they have the same specific surface area and the proportion of the reinforced anti-crack tendon is 0.95kg/cm³, the proportion of steel is 7.8g/cm³, under the condition of same adding volume, the weight of steel fiber is 8.0 times of the anti-crack tendon’s, so it is clear that use anti-crack tendon can reduce the cost quite a lot than use steel fiber.

 

 

Packing:

 

1.0kg/pe bag, 8kg/carton, 3200kg/20GP.
