White Polypropylene Concrete PP Mesh Fiber For Projects
Construction
PP Mesh Fiber Decription:
PP mesh fiber is a kind of polypropylene particles as raw
materials, through special processing made of fibers, they are
interwoven into a network. The addition of this fiber in concrete
or mortar can effectively control the early plastic shrinkage and
settlement cracks, improve the seepage resistance, crushing
resistance and impact resistance of concrete, enhance the toughness
and wear resistance of concrete, thus extending the life of
buildings and reducing maintenance costs.
PP Mesh Fiber Function:
1. Increase seepage resistance
2. Prolong endurance
3. Improve steel protection
4. Increase cracking resistance
5. Increase fire resistance
6. Strengthen spurt & fatigue
7. Improve tensile, bending & folding strength
8. Improve plastic deformity
9. Strong acid & alkali resistance and good endurance
PP Mesh Fiber 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.
