Biture Grey PP Fiber Twisted Bunchy Form For Reinforcement To
Crack-Resist And Concrete
Product Description
1. This fibre is used to instead of steel fiber for reinforcement
to cement concrete. Compared with steel fiber, it has the advantage
of easy
dispersing and blending, no damage to the mixing equipments, etc
2. The rigid polymer fibre is used polypropylene as its raw material,
produced the rough surface treatment by special parallel thread
extruding &
twisting process. It has high break strength, better dispersion and
strong combining ability, will be widely used to instead of steel
fibre to
reinforce the cement concrete and crack-resistant.
Application
1. The surface of road, bridge, runway and floor of the factory.
2. Wall and roof of the tunnel and mine.
3. Dam, river, bridge pier, dock and military protection
facilities.
Applying Instruction
1. Ration design of the fibre concrete:
Generally the recommended amount to add to the concrete is more
than 2.7kg per sqm (volume ratio is 0.3%), reinforcement adding
amount is
5.5kg, Compared with adding 47kg of steel fibre, 5.4kg polymer
fibre has the same volume ratio to the concrete.
2. Length:
54mm for common crack-resistant requirement.
3. Matching Ratio:
Usually, it is no need to Change the matching ratio of the
concrete. Considering the requirement of fissure-resistant, the
polymer fiber is recommend to combine with the PP fiber mesh form
with the volume ratio of 1:1(0.9kg fiber-mesh to per sqm of cement
concrete). .
4. Mixer Adoption:
Double-axle horizontal compelling mixer is priority.
5. 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 common concrete, but the stirring
time should be properly prolonged to make fiber com-pletely mixed
6. Shaping & Maintenance:
There is no special requirement, may along the vibrating time for
30s, The maintenance of the fibre concrete should be done same as
the normal
concrete.
