13mm Pp Polypropylene Mesh Fibrillated Concrete Reinforcement Fiber

Product Description

4mm 6mm 8mm 12mm 16mm 19mm 13mm 20mm pp polypropylene mesh Fibrillated concrete cement fibre fiber for cememt

polypropylene mesh fiber PROPERTIES:

with 100% virgin polypropylene as raw material,This fiber looks like a net structure with many fiber monofilaments connected.

When the fiber was mixed into concrete, the horizontal structure in fiber monofilament can be destroyed in the course of stirring                              owing to friction and rubbing, and the fiber monofilament or net-like structure will fully stretch, thus the concrete is reinforced by a                            great number (more than 7million pieces per sqm of polypropylene fibers.

polypropylene mesh fiber APPLICATIONS:

It is a kind of concrete-strengthening fiber, it become to popular subject in the field of fiber concrete research and application after glass fiber and steel fiber.

polypropylene mesh fiber Reinforced Functions to Concrete:

compared with steel fiber, full-dispersed polypropylene fiber has advantages in its thinness,

large amount, non-water absorbency, strong acid & alkali resistance and similar elastic modulus

with that of concrete.

polypropylene mesh fiber The reinforced functions run as follows:

◆Increase seepage resistance                       ◆Prolong endurance

◆Improve steel protection                               ◆Strengthen spurt & fatigue

◆Increase cracking resistance                        ◆Increase fire resistance

◆Improve tensile, bending & folding strength ◆Improve plastic deformity

◆Strong acid & alkali resistance and good endurance

Suitable Fields of polypropylene mesh fiber:

A). Projects like concrete road, bridge, airport road and basement like factory floor

which strictly require cracking resistance.

The life span of these projects will be more 5-10 years.

B). The walls of tunnels, mines, roofs and reservoir projects with special construction.

When using spray technology in concrete construction, the polypropylene 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 polypropylene 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.

polypropylene mesh fiber brief specification:

Relevant suggestion of application:

A)about length: Generally, the proper length of the fiber added into concrete is 18mm,

and in the spray concrete the proper length is 12mm.

B)Ratio design: Usual the proper amount of to concrete is 0.9kg/m3, the waterproof layer of the

bridge requires 1.20-1.8kg/m3, the spray concrete in the tunnel is also 1.8kg/m3. the fiber has

better effects on the concrete with active compound materials, such as silicon ash, coal powder,

ground slag and zeolite powder etc…

C)Mixer adoption: double-axle horizontal compelling mixer is better and self-dropping cylinder

mixer can be used too.

D)Mixing process: Crushed stones, fibers and sands are put into the mixer in succession,

after stirring for about 2-3 minutes, fiber will fully spread and then add cement and water

and stir again as normal process.

The addition of materials also can be put into as usual, but the stirring time should be prolonged

to more than 4 minutes to make the fiber completely dispersed.
