Polypropylene short fiber is also called anti-cracking fiber fiber building material fiber building fiber. Polypropylene short fiber is a high-strength bundled monofilament fiber made from polypropylene. Adding it to mortar concrete can effectively control micro-cracks caused by factors such as solid plastic shrinkage, drying shrinkage, temperature changes and other factors of concrete mortar, prevent and inhibit the formation and development of cracks, and greatly improve the crack resistance, impermeability, impact resistance and earthquake resistance of concrete

Specifications
Polypropylene short fibers can well improve the crack resistance, permeability resistance, erosion resistance, frost resistance and explosion resistance of mortar/concrete and improve the workability of concrete. Tens of millions of fibers are evenly distributed in the mortar/concrete and play a very good micro-reinforcement role. This maintains the overall structure of the structure and prevents the structure from being scattered into many fragments when it is damaged by impact, preventing The corrosion of steel bars in the structure can greatly extend the service life of the project and reduce the maintenance cost of the project.
The dosage of polypropylene short fiber is kg/cubic meter of mortar or concrete, usually kg/cubic meter of mortar or concrete. The amount of fiber should be different according to the different regions of the project site. For areas with severe freezing and thawing or areas with severe grinding, the amount should be higher.
