The main function of mesh polypropylene fibreTo improve the anti cracking performance of concrete - mesh polypropylene fibre;
The main use of mesh polypropylene fibre
High grade concrete pavement and the fence, bridge, factory floor cracking high requirements engineering can improve the road service life of 5~10 years, and can replace steel wire net;
The overpass, bridge pier, the main structure, which can effectively prevent early cracking, improve component toughness, impact resistance and anti-seismic capacity enhancement;
The bridge main structure and pavement, prevent cracking and to prevent unsafe because of vibration caused by;
Dam, the water conservancy and Hydropower Engineering in reducing spillway and diversion hole parts such as impermeability, require a higher impact resistance of concrete pouring engineering;
The airport runway, tarmac road -- can improve impact resistance and abrasion resistance of pavement cracks and decrease exponentially, due to the rupture of the small pieces of debris, avoid risks caused by the engine intake, improve the safety performance of aircraft;
Shotcrete - tunnel, subway, mine at the top of the wall and slope reinforcement, concrete pump, concrete rebound off, no more than 4%;
The military protection engineering, port, dock, yard, river, can significantly improve the shock resistance and anti fatigue ability, prevent cracking, prevent seepage.
The basement wall, floor and roofing; water channels, water reservoir; septic tank; swimming pool leak.
Recommended dosage of mesh polypropylene fibre
Concrete - usually dosage: 0.9Kg/m3; bridge waterproof layer, recommended dosage: 1.50 Kg/m3.
Using the method of mesh polypropylene fibre
Directly added, does not change the concrete mix in with other mixture before and after filling or adding mixer. Forced stirring time 2~3 minutes for a slightly longer than conventional mixing time, to ensure the uniform distribution of fibers.
