Synthetic 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.

Benefits

1. It can effectively reduce the risk of concrete cracks ;

2. Improve the tensile, flexural and flexural strength of concrete;

4. Reduce the fatal defects in concrete and improve the impermeability of concrete;

5. Protect the reinforcement from corrosion and improve the durability of concrete structure;

6. Increase the abrasion resistance of concrete;

7. The fatigue resistance is improved significantly;
