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.
