Polypropylene PP Twisted Bundle Fiber For Construction Concrete

Product Details

 Twisted Bundle PP Fiber is developed for replacement of steel fiber.

 With polypropylene as its raw material,it is produced by special drawing twisting and surface treatment.

 Compared with steel fiber, it has advantages of acid, alkali resistant, excellent tensile, easy dispersing, convenience for construction .

Parameter

Feature

* Prevent concrete cracks, like concrete road, bridge, airport and grade level

*Improve permeability resistance of concrete, walls of tunnels, mines,roofs and reservoir projects

*Improve concrete freezing-thawing resistance

*Improve impact resistance of concrete ,folding resistance, fatigue resistance, seismic performance

*Improve the durability of concrete and aging resistance

*Improve the fire performance of concrete

Product Instructions 

1. Dosage: No less than 3 kg/cubic meter of concrete for high crack level(volume ratio:0.3%) ;

for general level, it can use compound fiber of 0.8 kg Twisted Bundle PP Fiber and 0.4 kg PP fiber mesh.

2. String requirement: crushed stones, fibers and sands are put into the mixer in succession. After string for two minutes,fiber will fully spread and then add cement and water and stir normally.

The addition of materials can be put into as usual, but the stirring time should be properly prolonged to more than 4 minutes to make fiber completely mixed.

3.Package: 1 kg per bag, may packed according to radio with PP fiber mesh.

Application

1.The surface of road, bridge, runway and floor of the factory.

2. Wall and roof of the tunnel and mine.

3. Dam, river, bridge pier, dock and military protection facilities.
