Industrial cement polypropylene staple Fibrillated fibre for concrete reinforcing
polypropylene staple Fibrillated fibre PROPERTIES:
Polypropylene mesh fiber is a kind of polypropylene particle as raw material, which is made of bundles of interwoven fibers after special processing and treatment. After mixing, the fiber monofilament or mesh structure is fully opened and a kind of chaotic support system is formed inside the concrete. It can effectively control the early plastic shrinkage and settlement cracks of concrete and cement mortar. It greatly improves the impermeability, crushing resistance and impact resistance of concrete, strengthens the toughness and wear resistance of concrete, thus greatly prolongs the life of buildings and greatly reduces the cost of Engineering maintenance.
polypropylene staple Fibrillated fibre 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 staple Fibrillated fibre 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 staple Fibrillated fibreThe 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
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 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.
