Polypropylene fibers are polypropylene and other engineering materials synthetic fibers.
The main function of polypropylene fiber works :
1 to prevent concrete cracks
2 improved penetration resistance of concrete
Three freeze-thaw resistance of concrete to improve performance
4 improve concrete impact , bending , fatigue , seismic performance
5 to improve the durability of concrete, anti-aging
6 to improve the fire resistance of concrete
Polypropylene fibers are mainly used in the project :
A cement mortar, inside ( outside ) wall painting, plastering aerated concrete , interior decoration and insulation mortar putty .
2 Blast , fire engineering, air defense military engineering , oil platforms , chimneys, refractories.
3 shotcrete , tunnels, culverts, lining, thin-walled structures , slope reinforcement .
4 rigid self waterproof concrete structure, basement floor, side walls , roof, floor slab roofing , reservoirs, etc. . Crack resistance , impact resistance , abrasion resistance, high requirements engineering, hydraulic engineering , subway, airport runways , ports, Interchange viaduct deck , piers , long structure.
