With polypropylene as its raw material,fiber-mesh is produced by special technology.It appears net-like structure with many monofilaments connected.
The horizontal structure in monofilament can be destroyed in the course of the stirring owng to friction and rubbing,and the monofilament or net-like structure will fully stretch,thus the concrete is reinforce by a great number(more than 7 million pieces per cubic meter)of polypropylene fibers.
Applications
1,Concrete pavament,deck,airport runway,factory horizon
2,Shotcrete projects such as tunnel,mine wall,roof.
3,Irrigation work such as river,dam
4,Military protection,terminal revetment,bridge pier.
5,Concrete precast.
Applying Instruction
Length:Generally 20mm
Mix Process:Crushed stones,fibers and sands are put into the mixer in succession.After stirring two minutes,fiber will fully spread and then add cement and water and stir normally.The addition of materials also can be put into as usual,but the strring time should be properly prolonged to more than 4 minutes to make fiber completely mixed.
Shapping & Matintenance:There is no special requirement,may prolong the vibrating time for 30s.The maintenace of the fiber concrete should be done same as the normal concrete.
Package:0.9kg per bag,may packed as customer’s requirements.
