High Quality Polypropylene Fiber PP Fiber China Manufacturer
Polypropylene Fiber is a fiber with 4shapes mixing with concrete to reinforce the strength of concrete and crack resist.
Function Polypropylene Fiber:
Increase seepage resistance
Improve steel protection
Increase cracking resistance
Increase fire resistance
Strengthen spurt & fatigue
Improve tensile, bending & folding strength
Improve plastic deformity
Strong acid & alkali resistance and good endurance
A).Polypropylene Fiber is used in projects like concrete road, bridge, airport road and factory floor which strictly require cracking resistance. The life span of these projects will be lengthened for 5-10 years.
B). The walls of tunnels, mines, roofs and reservoir projects with special construction. When using spray technology in concrete construction, the PP fiber added into the concrete can effectively decrease the spray concrete's deformation rate of the walls less than 8% and that of the roof less than 12%, and also can reduce the friction. It can improve the constructing efficiency and working environment and popularize the spray technology.
C). River courses and dams, etc. The PP fiber can improve concrete's resistance to crack and squirt and wear to lengthen projects' life span.
D). Military defense works, dock banks and piers, etc. This fiber can greatly strengthen the concrete's spurt resistance and heighten these projects' safety and lengthen their life span.

Usage Polypropylene Fiber:
Length : Generally, the proper length of the fiber added into concrete is 20 mm, and in the spray concrete is 10mm.
Ratio Design: Usually the proper amount of fiber to concrete is 0.9kg/m3 , and the water-proof layer of the bridge requires 1.35-1.8kg/m3, and the spray concrete in the tunnel is also the same and other materials remain the same. The ratio of fiber and concrete can be determined by tests for special purposes. The fiber has better effects on the concrete with active compound materials, such as silicon ash, coal powder, ground slag and zeolite powder.
Mixer Adoption: Double-axle horizontal compelling mixer is better and self-dropping cylinder mixer can be used, too.
Mixing Process: Crushed stones, fibers and sands are put into the mixer in succession. After stirring for 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 stirring time should be properly prolonged to make fiber completely mixed.
Stirring Time: The purpose of the stirring is to make fiber fully spread into monofilament or the net fully spread, so generally the stirring time is 2-3minutes after the addition of polypropylene fiber-mes
