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

Polypropylene short fiber can be widely used in water conservancy hubs, hydropower stations, ports, terminals, river water conveyance channels, panel dams, spillways, diversion tunnels, bank reinforcements, slope reinforcements, dam surface repairs, etc. Concrete and shotcrete engineering. It is used to resist cracking and waterproofing of roofs and basements during house construction, to resist cracking of floor slabs and columns and beams, to resist cracking of mortar plastering surfaces of interior and exterior walls, to resist earthquakes and impact on factory floors, and to repair parts that are prone to explosion and repair of buildings. Concrete structures such as airports, municipal facilities, highways and bridges that are often impacted, as well as R products, European-style components, art sculptures, lightweight wall panels, pre-mixed mortar, etc.
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.
Higher strength and elastic modulus are beneficial to the mechanical properties of concrete.
It has strong binding force with the cement surface, and the hydrophilic treatment facilitates the hanging of dust and improves the strength.
Excellent dispersion and no clumping, effectively ensuring its anti-cracking performance.
The fiber has stable chemical properties and strong acid and alkali resistance.
