Application of Polypropylene Staple Fiber in Engineering
Polypropylene short fiber can be widely used in concrete and shotcrete projects such as water conservancy hub, hydropower station, port, wharf, river course, water conveyance channel, spillway, diversion tunnel, embankment reinforcement, slope reinforcement, dam surface repair, etc. Anti-cracking and waterproof of roof and basement in house construction, anti-cracking of floor slab, column and beam, anti-cracking of mortar plaster of internal and external walls, anti-seismic and anti-impact of factory floor, easy-to-burst parts and repair of buildings. Airports, municipal facilities, highways, bridges and other concrete structures that are often impacted and GRC products, European-style components, art sculptures, lightweight wall panels, pre-mixed mortar, etc.

Polypropylene short fiber can improve the crack resistance, impermeability, abrasion resistance, frost resistance and explosion resistance of mortar/concrete and improve the workability of concrete. Tens of millions of fibers are evenly distributed in mortar/concrete, which plays a good role in micro-reinforcement, so that the integrity of the structure is well maintained, and the structure is prevented from being scattered into many fragments when it is damaged by impact. 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.

Polypropylene short fiber content of 0.6-1.8kg/cubic meter of mortar or concrete, generally 0.9kg/cubic meter of mortar or concrete. According to the engineering parts of the region, the amount of fiber should be different, for the freeze-thaw comparison of the region and the impact of the parts of the disaster should be higher.
