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
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
◆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
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
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 brief specification:
|Density (g/cm3)||0.91+/-0.01||Elastic Modulas (mPa)||> 4000|
|Equivalent Diameter (um)||100||Shape||Beam-like Net|

Relevant suggestion of application:
A)about length: Generally, the proper length of the fiber added into concrete is
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
mixer can be used too.
D)Mixing process: Crushed stones, fibers and sands are put into the mixer in
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.
