Polypropylene Fiber Fibrillated Mesh
Product Description
Polypropylene Fiber (PP Fiber) is made from 100% virgin PP
granular, after extruding from different mould and technology, we
can get 4 different types of fiber, including Monofilament form,
Fibrillated Mesh form, Twisted Bunchy and Wave form with different
size. These fiber can improve the reinforcement of mortar or
concrete performance effectively to make them strong and protect
the projects.
Feature:
◆Increase seepage resistance
◆Prolong endurance
◆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
APPLYING INSTRUCTION:
1.Length : Generally, the proper length of the fiber added into
concrete is 20 mm, and in the spray concrete is 10mm.
2. 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.
3. Mixer Adoption: Double-axle horizontal compelling mixer is
better and self-dropping cylinder mixer can be used, too.
4. 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.
5. 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-mesh.
Suitable Project
A). 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.
