Synthetic Macro fiber
Product Description
1. Polypropylene Twist Macro Fiber is developed for replacement of
steel fiber, with polypropylene as its raw material;it is produced
by special drawing twisting and surface treatment. Compared with
steel fiber, it has advantages of acid, alkali resistant, excellent
tensile, easy dispersing, convenience for construction and no
damage to the mixing equipment.
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.
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.
