PP Macro fiber

Polypropylene macro fiber(PP Macro fiber) is synthetic fiber made by raw polypropylene. Compared with steel fiber, it has the characteristics of corrosion resistance, easy dispersion, easy construction and small consumption. After adding pp macro fiber into concrete, it overcomes the characteristics of low tensile strength, small ultimate elongation and brittleness. It has the properties of tensile strength, shear resistance, crack resistance, fatigue resistance and high toughness, and has been applied in construction, road and bridge, hydraulic engineering and other engineering fields.

 
 
Features
 
1. It can effectively reduce the risk of concrete cracks and improve the tensile, flexural and flexural strength of concrete;
 
2. When encountering earthquake and other severe natural disasters, it can reduce the damage;
 
3. Reduce the fatal defects in concrete and improve the impermeability of concrete;
 
4. Protect the reinforcement from corrosion and improve the durability of concrete structure;
 
5. Increase the abrasion resistance of concrete;
 
6. The fatigue resistance is improved significantly;

7.t is used for road damage of absolute tire. 

Application
 
1. Culvert support, mountain slope protection, etc;
 
2. It is used for basement seepage control, reservoir and low-pressure water pipeline engineering;
 
3. The spillway, stilling basin, gate bottom plate and other high-speed flow parts of water conservancy and hydropower projects;
 
4. Concrete with imitative steel fiber is made of synthetic material, which has the characteristics of steel fiber, so it has more advantages in concrete engineering under corrosive environment such as seawater;
 
5. Highway, railway bridge and other projects.
 
Dosage
 
1. Mixing amount: it is suggested that the volume content of concrete with imitation steel fiber is 0.3% - 0.9%, that is, 3kg-9kg per cubic meter of concrete.
 
2. Length selection: 30mm-50mm for general anti cracking reinforced concrete and 20mm-30mm for shotcrete.
